A Study in Depth of f0(1370)

Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Claims have been made that f0(1370) does not exist. The five primary sets of data requiring its existence are refitted. Major dispersive effects due to the opening of the 4pi threshold are included for the first time; the sigma -> 4pi amplitude plays a strong role. Crystal Barrel data on pbar-p -> 3pizero at rest require f0(1370) signals of at least 32 and 33 standard deviations in 1S0 and 3P1 annihilation respectively. Furthermore, they agree within 5 MeV for mass and width. Data on pbar-p -> eta-eta-pizero agree and require at least a 19 standard deviation contribution. This alone is sufficient to demonstrate the existence of f0(1370). BES II data for J/Psi -> phi-pi-pi contain a visible f0(1370) signal > 8 standard devations. In all cases, a resonant phase variation is required. The possibility of a second pole in the sigma amplitude due to the opening of the 4pi channel is excluded. Cern-Munich data for pi-pi elastic scattering are fitted well with the inclusion of some mixing between sigma, f0(1370) and f0(1500). The pi-pi widths for f2(1565), rho3(1690), rho3(1990) and f4(2040) are determined.

Perturbative renormalization of staggered fermion operators with stout improvement: Application to the magnetic susceptibility of QCD
Creators: name: (:Unkn) Unknown
Publisher: name: My University
Year: 2013
Subjects: hep-lat

description: We calculate the fermion propagator and the quark-antiquark Green's functions for a complete set of ultralocal fermion bilinears, Γ [Γ: scalar (S), pseudoscalar (P), vector (V), axial (A) and tensor (T)], using perturbation theory up to one-loop and to lowest order in the lattice spacing. We employ the staggered action for fermions and the Symanzik Improved action for gluons. From our calculations we determine the renormalization functions for the quark field and for all ultralocal taste-singlet bilinear operators. The novel aspect of our calculations is that the gluon links which appear both in the fermion action and in the definition of the bilinears have been improved by applying a stout smearing procedure up to two times, iteratively. Compared to most other improved formulations of staggered fermions, the above action, as well as the HISQ action, lead to smaller taste violating effects [1, 2, 3]. The renormalization functions are presented in the RI′ scheme; the dependence on all stout parameters, as well as on the coupling constant, the number of colors, the lattice spacing, the gauge fixing parameter and the renormalization scale, is shown explicitly. We apply our results to a nonperturbative study of the magnetic susceptibility of QCD at zero and finite temperature. In particular, we evaluate the "tensor coefficient", t, which is relevant to the anomalous magnetic moment of the muon.

description: We report new p(e, e′p)π̊ measurements in the Δ+(1232) resonance at the low momentum transfer region utilizing the magnetic spectrometers of the A1 Collaboration at MAMI. The mesonic cloud dynamics are predicted to be dominant and appreciably changing in this region while the momentum transfer is sufficiently low to be able to test chiral effective field theory calculations. The results disagree with predictions of constituent quark models and are in reasonable agreement with dynamical calculations with pion cloud effects, chiral effective field theory and lattice calculations. The reported measurements suggest that improvement is required to the theoretical calculations and provide valuable input that will allow their refinements. © Società Italiana di Fisica / Springer-Verlag 2013.

description: Ochotona hyperborea cinereoflava (Schrenk, 1858)
Lectotype (designated by Ognev 1940). ZIN 82201, skin with skull inside. Collected by M. Furman 18.02.1845 (Collection of A. F. Middendorff). Paralectotypes: ZIN 82202, male, skin with skull inside; 82203 sex unknown, broken skull and skin.
Type locality.— Russia, Khabarovsk Territory, lower Uda River, vicinities of Udskoe (“Udskoy ostrog”).
Description.— Pikas of the D genetic lineage; southern acoustic race. Occupying a central position in the species range, O. h. cinereoflava contacts four other subspecies (Supplementary Data SD7). It can be distinguished from O. h. hyperborea, O. h. uralensis, and O. h. fedoseevi ssp. n. by the shape of the frequency modulation curve of its alarm call (Fig. 6). Differences with O. h. uralensis include also the shape of the parietal suture of the skull (Fig. 5). Separation from O. h. cinereofusca is possible on the basis of genetic traits only.
Distribution.— KnownfromDzhugdzhurRangeandStanovoy Range; forms a zone of intergradation with O. h. cinereofusca on the Aldan Plateau. Theoretically (Supplementary Data SD7), O. h. cinereoflava should contact with O. h. uralensis at the northern foothills of the Aldan Plateau and western foothills of the Dzhugdzhur Range; and contact O. h. hyperborea to the north of the Dzhugdzhur Range. However, any such contact zones are not known.
Nomenclatural notes.— There only is one available name that has been described from the distribution range of this subspecies: Lagomys hyperboreus var. cinereoflava Schrenk, 1858. This taxon initially was described on the basis of three specimens (Schrenk 1858), collected from very remote areas (Lissovsky et al. 2003): “Udskoy Ostrog” (ca. 54.56°N, 134.27°E), Maya River (ca. 54.90°N, 133.91°E, 12.09.1845; collector, I. G. Woznessenskiy); and Olenek River (68.183°N, 112.25°E, 1.10.1854; collector, R. Maak). Both L. Schrenck and the museum label mention A. F. Middendorff as a collector of the specimen from Udskoy Ostrog. However, A. F. Middendorff collected animals in the Kamchatka Peninsula during this time (Sokolov and Shishkin 2005). His assistant M. Furman was left in Udskoe for collections and observations; most probably he was the real collector of the specimen.

description: Charge density wave (CDW) instability is often found in phase diagrams of superconductors such as cuprates and certain transition-metal dichalcogenides. This proximity to superconductivity triggers the question on whether CDW instability is responsible for the pairing of electrons in these superconductors. However, this issue remains unclear and new systems are desired to provide a better picture. Here, we report the temperature-pressure phase diagram of a recently discovered BiS$_2$ superconductor La$_2$O$_2$Bi$_3$AgS$_6$, which shows a possible CDW transition at $T^*\sim$155 K and a superconducting transition at $T_c\sim$1.0 K at ambient pressure, via electrical resistivity measurements. Upon applying pressure, $T^*$ decreases linearly and extrapolates to 0 K at 3.9 GPa. Meanwhile, $T_c$ is enhanced and reaches maximum value of 4.1 K at 3.1 GPa, forming a superconducting dome in the temperature-pressure phase diagram.

description: This monograph derives direct and concrete relations between colored Jones polynomials and the topology of incompressible spanning surfaces in knot and link complements. Under mild diagrammatic hypotheses that arise naturally in the study of knot polynomial invariants (A- or B-adequacy), we prove that the growth of the degree of the colored Jones polynomials is a boundary slope of an essential surface in the knot complement. We show that certain coefficients of the polynomial measure how far this surface is from being a fiber in the knot complement; in particular, the surface is a fiber if and only if a particular coefficient vanishes. Our results also yield concrete relations between hyperbolic geometry and colored Jones polynomials: for certain families of links, coefficients of the polynomials determine the hyperbolic volume to within a factor of 4. Our approach is to generalize the checkerboard decompositions of alternating knots. Under mild diagrammatic hypotheses (A- or B-adequacy), we show that the checkerboard knot surfaces are incompressible, and obtain an ideal polyhedral decomposition of their complement. We employ normal surface theory to establish a dictionary between the pieces of the JSJ decomposition of the surface complement and the combinatorial structure of certain spines of the checkerboard surface (state graphs). Since state graphs have previously appeared in the study of Jones polynomials, our setting and methods create a bridge between quantum and geometric knot invariants.

description: We present {\it Chandra} HETG observations of SS Cygni in quiescence and outburst. The spectra are characterized by He-like and H-like Ka emission lines from O to Fe, as well as L-shell emission lines from Fe. In quiescence, the spectra are dominated by the H-like Ka lines, whereas in outburst the He-like lines are as intense as the H-like lines. In outburst, the H-like Ka lines from O to Si are broad, with widths of 4--14 eV in Gaussian $σ$ (1800--2300$ {\rm km s^{-1}}$). The large line widths, together with line profiles, indicate that the line-emitting plasma is associated with the Keplerian disk and still retains the azimuthal bulk motion. In quiescence, the emission lines are narrower, with a Gaussian $σ$ of 1--3 eV (420--620$ {\rm km s^{-1}}$). A slightly larger velocity for lighter elements suggests that the lines in quiescence are emitted from an ionizing plasma at the entrance of the boundary layer, where the bulk motion of the optically thick accretion disk is converted into heat due to friction. Using the line intensity ratio of He-like and H-like Ka lines for each element, we have also investigated the temperature distribution in the boundary layer both in quiescence and outburst. The distribution of SS Cyg is found to be consistent with other dwarf novae investigated systematically with {\it ASCA} data.

description: Within the collinear twist-3 framework, we analyze the double-spin asymmetry in collisions between longitudinally polarized nucleons and transversely polarized nucleons with focus on hadron and jet production. As was the case in direct photon production, the double-spin dependent cross section for hadron and jet production has the advantage of involving a complete set of collinear twist-3 functions for a transversely polarized nucleon. In addition, we outline further benefits of this observable for a potential future measurement at the Relativistic Heavy Ion Collider, which includes insight on the gluon helicity distribution as well as information on the Efremov-Teryaev-Qiu-Sterman function TF(x,x) that plays a crucial role in single-spin asymmetries. © 2012 American Physical Society.
Ionizing Photon Escape Fractions from High Redshift Dwarf Galaxies

description: It has been argued that low-luminosity dwarf galaxies are the dominant source of ionizing radiation during cosmological reionization. The fraction of ionizing radiation that escapes into the intergalactic medium from dwarf galaxies with masses less than ~10^9.5 solar masses plays a critical role during this epoch. Using an extensive suite of very high resolution (0.1 pc), adaptive mesh refinement, radiation hydrodynamical simulations of idealized and cosmological dwarf galaxies, we characterize the behavior of the escape fraction in galaxies between 3 x 10^6 and 3 x 10^9 solar masses with different spin parameters, amounts of turbulence, and baryon mass fractions. For a given halo mass, escape fractions can vary up to a factor of two, depending on the initial setup of the idealized halo. In a cosmological setting, we find that the time-averaged photon escape fraction always exceeds 25% and reaches up to 80% in halos with masses above 10^8 solar masses with a top-heavy IMF. The instantaneous escape fraction can vary up to an order of magnitude in a few million years and tend to be positively correlated with star formation rate. We find that the mean of the star formation efficiency times ionizing photon escape fraction, averaged over all atomic cooling (T_vir > 8000 K) galaxies, ranges from 0.02 for a normal IMF to 0.03 for a top-heavy IMF, whereas smaller, molecular cooling galaxies in minihalos do not make a significant contribution to reionizing the universe due to a much lower star formation efficiency. These results provide the physical basis for cosmological reionization by stellar sources, predominately atomic cooling dwarf galaxies.

description: Hydrogen is seen as a key tool for achieving energy system decarbonisation. The opportunities it represents for clean industry and energy security are widely understood, as evidenced by its inclusion in two hallmark pieces of clean energy legislation: the EU Green Deal, and the US Government’s Inflation Reduction Act. Despite this, many of the challenges to be overcome in developing a clean hydrogen industry are not yet deeply understood. There remains much uncertainty about how policy can best enable the rapid scale-up required of the industry to deliver on ambitious climate targets. The work described in this thesis aims to investigate the challenges and opportunities of the burgeoning clean hydrogen industry through comprehensive techno-economic analysis of hydrogen production, storage, and supply, with a particular focus on the island of Ireland. The work identifies that hydrogen storage has not been adequately considered in much of the analysis of hydrogen supply chains, and key implications for hydrogen cost and emissions footprint therefore not discovered. Calculated levelised cost of renewable hydrogen in 2030 varies from €3.90-12.40/kgH2 depending on storage technology. In addition, the work highlights how grid-connected hydrogen production can operate flexibly based on market prices, producing low-cost, low-carbon hydrogen. A levelised cost of €2.05/kg for 2030 can be achieved, with carbon intensities lower than 1 gCO2/gH2 for grid-connected electrolysis in an 80% renewable power system. The sheer scale of investment and relatively short timelines required to deploy hydrogen infrastructure on the island of Ireland to meet climate targets are also outlined. Estimated hydrogen demand in Ireland in 2050 ranges from 36 TWh to 116 TWh. For context, natural gas consumption in the Republic of Ireland was 51 TWh in 2021. These findings underline the key considerations faced by project developers and policymakers alike in realising hydrogen’s role in decarbonisation. The challenges faced by hydrogen storage must be overcome through innovation and forward-thinking policy, whilst policy is also crucial in enabling system integration to ensure hydrogen plays a role in achieving clean, affordable, and secure energy for all.
MgB2 nonlinear properties investigated under localized high rf magnetic field excitation

description: The high transition temperature and low surface resistance of MgB 2 attracts interest in its potential application in superconducting radio frequency accelerating cavities. However, compared to traditional Nb cavities, the viability of MgB2 at high rf fields is still open to question. Our approach is to study the nonlinear electrodynamics of the material under localized rf magnetic fields. Because of the presence of the small superconducting gap in the π band, the nonlinear response of MgB2 at low temperature is potentially complicated compared to a single-gap s-wave superconductor such as Nb. Understanding the mechanisms of nonlinearity coming from the two-band structure of MgB2, as well as extrinsic sources of nonlinearity, is an urgent requirement. A localized and strong rf magnetic field, created by a magnetic write head, is integrated into our nonlinear-Meissner-effect scanning microwave microscope. MgB2 films with thickness 50 nm, fabricated by a hybrid physical-chemical vapor deposition technique on dielectric substrates, are measured at a fixed location and show a strongly temperature-dependent third harmonic response. We propose that several possible mechanisms are responsible for this nonlinear response.

description: Ochotona hyperborea fedoseevi, ssp. nov. Lissovsky
Holotype.— Zoological Museum of Moscow State University S-194595, subadult male, skin and skull (Figs. 8 and 9). Collected by A. A. Lissovsky and E. V. Obolenskaya 12 September 2014 at Russia: Khabarovsk Territory; Bureinskiy Range, Bolshoy Suluk Lake; 51.301 N, 134.333 E.
Etymology.— The name is given in honor of famous land surveyor G. A. Fedoseev, who made a great contribution to the description of the Russian Far East; his popular books gave impulse to several generations of investigators to explore this territory.
Diagnosis.— The new subspecies can be distinguished from the rest O. hyperborea (except for Ochotona hyperborea yesoensis) by the specific shape of the frequency modulation curve of alarm call: the frequency grows first, then decreases (Fig. 6); ascending branch of the curve prevails over descending. Maximum of basal frequency is above 5500 Hz. Representatives of the new subspecies form separate clade E in the molecular phylogenetic analysis (Figs. 1 and 3).
Description.— The new subspecies cannot be distinguished from remaining O. hyperborea by morphological traits; the identification should be carried out on the basis of bioacoustic and genetic features described in the diagnosis.
The dorsal parts of pikas in summer fur are reddish brown, ventral parts are ochraceous. The dorsal parts of winter specimens are gray brown with darker median stripe, sides are sandy, ventral parts are gray or sandy. Fur near eyes is gray. Condylobasal length 37.3 mm (35.4–39); zygomatic breadth 20.0 mm (18.9–20.7).
Distribution.— Inhabits a number of mountain ranges in the Russian Far East—from the left bank of the lower Amur River to Tukuringra Range in the west: Djaki-Unakhta-Yanbiyana, Bureinskiy, Turana, Ezop, Tukuringra–Dzhagdy, and closely situated mountain ranges and uplands. The northern limit of the distribution goes along the Uda River Valley and Verkhnezeyskaya Plain. The Tukuringra Range population bears mitotypes of O. h. cinereofusca. The contact zone with O. h. cinereoflava has not yet been found, our model suggests this zone should be situated in the area of the upper Aldan River.
Nomenclatural notes.— No available names have been previously described from the distribution range of this subspecies. We therefore describe a new subspecies herein.

description: We report the measurement of the anisotropic ac polarizability of ultracold polar K40Rb87 molecules in the ground and first rotationally excited states. Theoretical analysis of the polarizability agrees well with experimental findings. Although the polarizability can vary by more than 30%, a "magic" angle between the laser polarization and the quantization axis is found where the polarizability of the |N=0,mN=0? and the |N=1,mN=0? states match. At this angle, rotational decoherence due to the mismatch in trapping potentials is eliminated, and we observe a sharp increase in the coherence time. This paves the way for precise spectroscopic measurements and coherent manipulations of rotational states as a tool in the creation and probing of novel quantum many-body states of polar molecules. © 2012 American Physical Society.

description: We consider the effect of strong external electromagnetic fields on thermodynamic observables in QCD, through lattice simulations with 1+1+1 flavors of staggered quarks at physical quark masses. Continuum extrapolated results are presented for the light quark condensates and for their tensor polarizations, as functions of the temperature and the magnetic field. We find the light condensates to undergo inverse magnetic catalysis in the transition region, in a manner that the transition temperature decreases with growing magnetic field. We also compare the results to other approaches and lattice simulations. Furthermore, we relate the tensor polarization to the spin part of the magnetic susceptibility of the QCD vacuum, and show that this contribution is diamagnetic. © Copyright owned by the author(s).
Role of electronic excitations in ground-state-forbidden inelastic collisions between ultracold atoms and ions

description: The role of electronic excitation in inelastic collisions between ultracold Ca atoms and Ba+ ions, confined in a hybrid trap, is studied for the first time. Unlike previous investigations, this system is energetically precluded from undergoing inelastic collisions in its ground state, allowing a relatively simple experimental determination and interpretation of the influence of electronic excitation. It is found that while the electronic state of the ion can critically influence the inelastic collision rate, the polarizability mismatch of the neutral atom electronic states suppresses short-range collisions, and thus inelastic processes, involving electronically excited neutral atoms. As a result of these features, it is experimentally demonstrated that it is possible to mitigate inelastic collision loss mechanisms in these systems, marking an important step toward long-lived hybrid atom-ion devices. © 2012 American Physical Society.

description: Ever since the first discoveries of the quantum-interference transport in mesoscopic systems, the electron dephasing times, $τ_ϕ$, in the concentrated AuPd alloys have been extensively measured. The samples were made from different sources with different compositions, prepared by different deposition methods, and various geometries (1D narrow wires, 2D thin films, and 3D thickfilms) were studied. Surprisingly, the low-temperature behavior of $τ_ϕ$ inferred by different groups over two decades reveals a systematic correlation with the level of disorder of the sample. At low temperatures, where $τ_ϕ$ is (nearly) independent of temperature, a scaling $τ_ϕ^{\rm max} \propto D^{-α}$ is found, where $tau_ϕ^{\rm max}$ is the maximum value of $τ_ϕ$ measured in the experiment, $D$ is the electron diffusion constant, and the exponent $α$ is close to or slightly larger than 1. We address this nontrivial scaling behavior and suggest that the most possible origin for this unusual dephasing is due to dynamical structure defects, while other theoretical explanations may not be totally ruled out.

description: Ochotona hyperborea yesoensis Kishida, 1930
Ochotona yoshikurai Kishida, 1932
Holotype.— Botanic Garden and Museum, Field Science Center for Northern Biosphere, Hokkaido University HUNHM06803, adult male. Collected by Forestry Bureau of the Hokkaido Government Office in 11 October 1928.
Type locality.— “In Prov. Kitami, a northern part of that Island ” (Kishida 1930). Notsukeushi, Kitami according to the specimen label.
Description.— Pikas of the F genetic lineage; eastern acoustic race. Separation from the only spatial neighbor of this subspecies: O. h. fedoseevi ssp. n., is possible on the basis of genetic traits only.
Distribution.— Sikhote-Alin Range, Sakhalin, and Hokkaido Islands. The range of this subspecies is isolated from those of other subspecies of northern pikas.
Nomenclatural notes.— No available names were described from the mainland part of this subspecies’ distribution. Sakhalin pikas were described as Ochotona yoshikurai Kishida, 1932. The nominal taxon Ochotona yesoensis Kishida, 1930, was described from Hokkaido Island; that region was not included in this study (except for bioacoustics). Nevertheless, Kartavtseva et al. (2014) analyzed the Cytochrome b gene of pikas from south of Russian Far East (genetic lineage F in our study) and Hokkaido Island and concluded that pikas from Hokkaido, Sakhalin, and Sikhote-Alin represent the same phylogenetic clade. From the position of bioacoustics, it is known that pikas from Hokkaido belong to the eastern acoustic race (Kawamichi 1981; Lissovsky 2005; this study). Thus, there is no information about any taxonomic peculiarities with respect to the Japanese pika, and we consider it to belong to the same subspecies as pikas from mainland Sikhote-Alin Range and Sakhalin Island. The name Ochotona yesoensis Kishida, 1930 is the senior synonym for the pikas from the distribution range of this subspecies.

Sufficient conditions for optimal control and the generalized problem of Bolza
Creators: name: Zeidan, Vera Michel
Publisher: name: University of British Columbia

description: We develop in this thesis four sufficiency criteria for the generalized problem of Bolza. These results represent a unification, in the sense that they can be applied to both the calculus of variations and to optimal control problems, as well as to problems with nonsmooth data. The first criterion, "point convexity", extends the convexity approach of Rockafellar. However, we derive a "Hamiltonian-Jacobi" approach which can be applied when the point convexity assumption fails to be satisfied. The method employed for this criterion brings to light a new point of view concerning the Jacobi condition in the classical calculus of variations. The latter can be considered as a condition which guarantees the existence of a canonical transformation transforming the original Hamiltonian to a locally concave-convex Hamiltonian. The third sufficiency criterion is an extension of the Hamilton-Jacobi approach from optimal control to the generalized problem of Bolza. This result gives rise to another sufficiency criterion in terms of a certain inequality. Our theorems on sufficient conditions are closely related. We prove that under certain assumptions the last three approaches can be unified. By this we mean that their hypotheses are equivalent. However, the point convexity, and hence the convexity, criterion turns out to have the most restrictive hypotheses of the four. The generality of the theorems proven stems to a great extent from the fact that not only non-differentiable but even infinite- valued functions are allowed in the treatment. The utility of using such functions appears when we apply these theorems to optimal control problems.

description: The outbreak of novel coronavirus disease (COVID- 19) has claimed millions of lives and has affected all aspects of human life. This paper focuses on the application of deep learning (DL) models to medical imaging and drug discovery for managing COVID-19 disease. In this article, we detail various medical imaging-based studies such as X-rays and computed tomography (CT) images along with DL methods for classifying COVID-19 affected versus pneumonia. The applications of DL techniques to medical images are further described in terms of image localization, segmentation, registration, and classification leading to COVID-19 detection. The reviews of recent papers indicate that the highest classification accuracy of 99.80% is obtained when InstaCovNet-19 DL method is applied to an X-ray dataset of 361 COVID-19 patients, 362 pneumonia patients and 365 normal people. Furthermore, it can be seen that the best classification accuracy of 99.054% can be achieved when EDL_COVID DL method is applied to a CT image dataset of 7500 samples where COVID-19 patients, lung tumor patients and normal people are equal in number. Moreover, we illustrate the potential DL techniques in drug or vaccine discovery in combating the coronavirus. Finally, we address a number of problems, concerns and future research directions relevant to DL applications for COVID-19.

description: We explore the zero temperature phase behavior of a two-dimensional two-component atomic Fermi gas with population and mass imbalance in the regime of the BEC-BCS crossover. Working in the mean-field approximation, we show that the normal and homogeneous balanced superfluid phases are separated by an inhomogeneous superfluid phase of Fulde-Ferrel-Larkin-Ovchinnikov (FFLO) type. We obtain an analytical expression for the line of continuous transitions separating the normal and inhomogeneous FFLO phases. We further show that the transition from the FFLO phase to the homogeneous balanced superfluid is discontinuous leading to phase separation. If the species have different masses, the superfluid phase is favored when the lighter species is in excess. We explore the implications of these findings for the properties of the two-component Fermi gas in the atomic trap geometry. Finally, we compare and contrast our findings with the predicted phase behavior of the electron-hole bilayer system.

description: Factorization theorems allow to separate out the universal, non-perturbative content of the hadronic cross section from its perturbative part, which can be computed in perturbative QCD, up to the desired order. In this paper, we derive a rigorous proof of factorization of the $e^+ e^- \to h\,X$ cross section, sensitive to the transverse momentum of the detected hadron with respect to the thrust axis, in a completely general framework, based on the Collins-Soper-Sterman approach. The results are explicitly computed to NLO-NLL accuracy and subsequently generalized to all orders in perturbation theory. This procedure naturally leads to a partition of the $e^+ e^- \to h\,X$ kinematics into three different regions, each associated to a different factorization theorem. In one of these regions, which covers the central and widest range, the factorization theorem has a new structure, which shares the features of both TMD and collinear factorization schemes. In the corresponding cross section, the role of the rapidity cut-off is investigated, as its physical meaning becomes increasingly evident. An algorithm to identify these three kinematic regions, based on ratios of observable quantities, is provided.

Single-spin asymmetries in inclusive deep inelastic scattering and multiparton correlations in the nucleon

Subjects: hep-ph

description: Transverse single-spin asymmetries in inclusive deep inelastic lepton-nucleon scattering can be generated through multiphoton exchange between the leptonic and the hadronic part of the process. Here we consider the two-photon exchange and mainly focus on the transverse target spin asymmetry. In particular, we investigate the case where two photons couple to different quarks. Such a contribution involves a quark-photon-quark correlator in the nucleon, which has a (model-dependent) relation to the Efremov-Teryaev-Qiu- Sterman quark-gluon-quark correlator T F. Using different parametrizations for T F we compute the transverse target spin asymmetries for both a proton and a neutron target and compare the results to recent experimental data. In addition, potential implications for our general understanding of single-spin asymmetries in hard scattering processes are discussed. © 2012 American Physical Society.

description: Old open clusters are very useful targets to investigate mechanisms responsible for lithium (Li) depletion during the main sequence. Comparison of the Li abundances in clusters of different age allows us to understand the efficiency of the Li destruction process. Our goal is the determination of membership and Li abundance in a sample of candidate members of the open cluster NGC 3960 (age ~1 Gyr), with the aim to fill the gap between 0.6 and 2 Gyr in the empirical description of the behavior of the average Li abundance as a function of the stellar age. We use VLT/FLAMES Giraffe spectra to determine the radial velocities and thus the membership of a sample of 113 photometrically selected candidate cluster members. From the analysis of the Li line we derive Li abundances for both cluster members and non-members. 39 stars have radial velocity consistent with membership, with an expected fraction of contaminating field stars of about 20%. Li is detected in 29 of the RV members; we consider these stars as cluster members, while we make the reasonable assumption that the remaining 10 RV members without Li, are among the contaminating stars. Li abundances of the stars hotter than about 6000 K are similar to those of stars in the Hyades, while they are slightly smaller for cooler stars. This confirms that NGC 3960 is older than the Hyades. The average Li abundance of stars cooler than about 6000 K indicates that the Li Pop. I plateau might start already at ~1 Gyr rather than 2 Gyr that is the upper limit previously derived in the literature. We also find that the fraction of field stars with high Li abundance (>1.5) is about one third of the whole sample, which is in agreement with previous estimates. The fraction of contaminating field stars is consistent with that previously derived by us from photometry.

description: It was our objective to analyze the perceived physical and motor competence in 10- to 13-year-old Spanish children, and to validate to the Spanish language and context the questionnaire of Scrabis-Fletcher and Silverman (2010). The perception of competence was analysed in 27 schools of Albacete (Spain), with a total of 389 boys and 391 girls, whose age ranged from 10 to 13 (average=11.08 and SD=0.43). Different analyses were performed, starting with a forward analysis of the items, using graphics and statistics. After this, an internal consistence study was performed, through Cronbach's alpha, using a multilevel package, version 2.3. Finally, the constructs structure was analyzed through a factorial confirmatory analysis (FCA), which used a Lavaan package, version 0.5-11. The consistence was high as a whole (Cronbach's alpha: 0.74). There was a high correlation between all items, even those from different factors. Regarding the analysis of students´ perceived physical and motor competence, the best values were obtained in the perceptions they had about their teachers and classmates, although they had worse values about their own personal experiences. Two questionnaires of 2 and 3 factors, using 7 and 14 items, respectively were established. Therefore, the instrument Perception of Competence in Middle School Physical Education was validated within the Spanish social context. The main practical application is the possibility of using this questionnaire in the PE lessons in Spain to know and increase the perceived physical and motor competence of the children.
