Searching for the Scalar Glueball

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Existence of gluonic resonances is among the early expectations of QCD. Today, QCD calculations predict the lightest glueball to be a scalar state with mass within a range of about 900-1700 MeV but there is no consensus about its experimental evidence. In a re-analysis of the phase shifts for pi pi scattering up to 1800 MeV where such states should show up we find the broad resonance f_0(600)/σcontributing to the full mass range and the narrow f_0(980) and f_0(1500) but no evidence for f_0(1370). Phenomenological arguments for the broad state to be a glueball are recalled. It is argued that the large radiative width of f_0(600)/σreported recently is not in contradiction to this hypothesis but is mainly due to pi pi rescattering. The small ``direct'' radiative component is consistent with QCD sum rule predictions for the light glueball.

description: We consider global geometric properties of a codimension one manifold embedded in Euclidean space, as it evolves under an isotropic and volume preserving Brownian flow of diffeomorphisms. In particular, we obtain expressions describing the expected rate of growth of the Lipschitz-Killing curvatures, or intrinsic volumes, of the manifold under the flow. These results shed new light on some of the intriguing growth properties of flows from a global perspective, rather than the local perspective, on which there is a much larger literature.

description: Every 19 years, Saturn passes through Jupiter's 'flapping' magnetotail. Here, we report Chandra X-ray observations of Saturn planned to coincide with this rare planetary alignment and to analyse Saturn's magnetospheric response when transitioning to this unique parameter space. We analyse three Director's Discretionary Time (DDT) observations from the High Resolution Camera (HRC-I) on-board Chandra, taken on November 19, 21 and 23 2020 with the aim to find auroral and/or disk emissions. We infer the conditions in the kronian system by looking at coincident soft X-ray solar flux data from the Geostationary Operational Environmental Satellite (GOES) and Hubble Space Telescope (HST) observations of Saturn's ultraviolet (UV) auroral emissions. The large Saturn-Sun-Earth angle during this time would mean that most flares from the Earth-facing side of the Sun would not have impacted Saturn. We find no significant detection of Saturn's disk or auroral emissions in any of our observations. We calculate the 3$σ$ upper band energy flux of Saturn during this time to be 0.9 - 3.04 $\times$ 10$^{14}$ erg cm$^{-2}$ s$^{-1}$ which agrees with fluxes found from previous modelled spectra of the disk emissions. We conclude by discussing the implications of this non-detection and how it is imperative that the next fleet of X-ray telescope (such as Athena and the Lynx mission concept) continue to observe Saturn with their improved spatial and spectral resolution and very enhanced sensitivity to help us finally solve the mysteries behind Saturn's apparently elusive X-ray aurora.

description: Highly magnified lensed galaxies allow us to probe the morphological and spectroscopic properties of high-redshift stellar systems in great detail. However, such objects are rare, and there are only a handful of lensed galaxies which are bright enough for a high-resolution spectroscopic study with current instrumentation. We report the discovery of a new massive lensing cluster, SDSS J120923.7+264047, at z=0.558. Present around the cluster core, at angular distances of up to ~40'', are many arcs and arc candidates, presumably due to lensing of background galaxies by the cluster gravitational potential. One of the arcs, 21'' long, has an r-band magnitude of 20, making it one of the brightest known lensed galaxies. We obtained a low-resolution spectrum of this galaxy, using the Keck-I telescope, and found it is at redshift of z=1.018.

description: We show how quasiprobability distribution functions defined over $N^{2}$-dimensional discrete phase spaces can be used to treat physical systems described by a finite space of states which exhibit spin tunneling effects. This particular approach is then applied to the Lipkin-Meshkov-Glick model in order to obtain the time evolution of the discrete Husimi function, and as a by-product the energy gap for a symmetric combination of ground and first excited states. Moreover, we also show how an angle-based potential approach can be efficiently employed to explain qualitatively certain features of the energy gap in terms of a spin tunneling. Entropy functionals are also discussed in this context. Such results reinforce not only the formalism per se but also the possibility of some future potential applications in other branches of physics.

description: Interstellar chemistry in low metallicity environments is crucial to understand chemical processes in the past metal-poor universe. Recent studies of interstellar molecules in nearby low-metallicity galaxies have suggested that the metallicity has a significant effect on chemistry of star-forming cores. Here we report the first detection of a hot molecular core in the extreme outer Galaxy, which is an excellent laboratory to study star formation and interstellar medium in a Galactic low-metallicity environment. The target star-forming region, WB89-789, is located at the galactocentric distance of 19 kpc. Our ALMA observations in 241-246, 256-261, 337-341, and 349-353 GHz have detected a variety of carbon-, oxygen-, nitrogen-, sulfur-, and silicon-bearing species, including complex organic molecules (COMs) containing up to nine atoms, towards a warm (>100 K) and compact (<0.03 pc) region associated with a protostar (~8x10^3 L_sun). Deuterated species such as HDO, HDCO, D2CO, and CH2DOH are also detected. A comparison of fractional abundances of COMs relative to CH3OH between the outer Galactic hot core and an inner Galactic counterpart shows a remarkable similarity. On the other hand, the molecular abundances in the present source do not resemble those of low-metallicity hot cores in the Large Magellanic Cloud. The results suggest that a great molecular complexity exists even in a primordial environment of the extreme outer Galaxy. The detection of another embedded protostar associated with high-velocity SiO outflows is also reported.

description: It is usually assumed that the quantum state is sufficient for deducing all probabilities for a system. This may be true when there is a single observer, but it is not true in a universe large enough that there are many copies of an observer. Then the probability of an observation cannot be deduced simply from the quantum state (say as the expectation value of the projection operator for the observation, as in traditional quantum theory). One needs additional rules to get the probabilities. What these rules are is not logically deducible from the quantum state, so the quantum state itself is insufficient for deducing observational probabilities. This is the measure problem of cosmology.

The modified substitute structure method as a design aid for seismic resistant coupled structural walls
Creators: name: Metten, Andrew W. F.
Publisher: name: University of British Columbia
Year: 2010

description: The modified substitute structure method is presented as a design aid which evaluates ductility requirements and deflections to determine the suitability of a reinforced concrete structural wall to withstand an anticipated siesmic disturbance. The procedure is analogous to elastic modal analysis but is an iterative technique which takes account of the stiffness loss of those members attempting to carry moments in .excess of their ultimate moment capacity. Unlike the elastic modal analysis procedure, the method is capable of predicting the ductility demand in individual members of a given strength. This is the appropriate form of the problem for coupled walls. The modified substitute structure method is applied through a computer program and the testing of this program is described. The effectiveness of the method for predicting ductlity demands and other parameters relating to structures undergoing inelasic behavior is evaluated by comparision with results obtained from the time step analysis program DRAIN-2D. The modified substitute structure method is a procedure which is inexpensive to use and could be applied easily in a non-research design environment.

description: The article is devoted to the study of the emotional sphere of children with autism spectrum disorders (ASD) and mental retardation (PDD). The content of diagnostics is disclosed, the analysis of the results revealing the description of emotional states depending on the dominant agro-industrial complex in children with PDD and ASD is carried out. The leading affective-behavioral complexes (APC) have been identified: psychophysiological sur-vival; symbiotic; expansion; play-dialogical and affection; figurative and role-playing. The article concludes that in children with ASD and PDD, the same APC can dominate and be impaired, but they are characterized by dif-ferent behavioral manifestations and emotional states. For children with ASD, rigid patterns of behavior are more characteristic; violation of stereotyped actions causes displeasure or negativism. In children with CRD, the pres-ence of a habitual rhythm activates activity, causing a positive emotional background. In children with CRD, several competing types of behavior can be triggered, from which short-lived and very mobile subcomplexes are formed, while new bundles of behavior quickly disintegrate.

description: BACKGROUND: Accurate knowledge of the core components of substitution rates is of vital importance to understand genome evolution and dynamics. By performing a single-genome and direct analysis of 39,894 retrotransposon remnants, we reveal sequence context-dependent germline nucleotide substitution rates for the human genome. RESULTS: The rates are characterised through rate constants in a time-domain, and are made available through a dedicated program (Trek) and a stand-alone database. Due to the nature of the method design and the imposed stringency criteria, we expect our rate constants to be good estimates for the rates of spontaneous mutations. Benefiting from such data, we study the short-range nucleotide (up to 7-mer) organisation and the germline basal substitution propensity (BSP) profile of the human genome; characterise novel, CpG-independent, substitution prone and resistant motifs; confirm a decreased tendency of moieties with low BSP to undergo somatic mutations in a number of cancer types; and, produce a Trek-based estimate of the overall mutation rate in human. CONCLUSIONS: The extended set of rate constants we report may enrich our resources and help advance our understanding of genome dynamics and evolution, with possible implications for the role of spontaneous mutations in the emergence of pathological genotypes and neutral evolution of proteomes.

Comparing Estimates of Wind Turbine Fatigue Loads using Time-Domain and Spectral Methods

Publisher: name: Sage Journals
Year: 2007
Subjects: fatigue AND wind turbine AND spectral

description: Fatigue analysis for wind turbines is typically carried out in the time domain, using cycle counting techniques such as ASTM’s Rainflow Cycle-Counting Algorithm. As an alternative, earlier workers investigated the feasibility of estimating wind turbine fatigue loads using spectral techniques such as Dirlik’s method to estimate stress range probability distributions that are based on spectral moments of the load in question. The present paper re-examines this approach with a particular view to assessing its limitations and advantages in the context of modern, large-scale wind turbines and design methods. These relative advantages are considered in terms of accuracy, statistical reliability, and efficiency of calculation. Field data on loads from a utility-scale 1.5 MW turbine near Lamar, Colorado in the Colorado Green Wind Farm are analyzed here as a representative example. The results show that valuable and reliable information about tower loads can be obtained very efficiently. By contrast, the limitations of the Dirlik method are highlighted by poor results for edgewise blade loads.
The variation of ground snow loads with elevation in southern British Columbia
Creators: name: Claus, Bernhard Ralph
Publisher: name: University of British Columbia
Year: 2010

description: Measurements conducted at 20 locations in Southern British Columbia were used to investigate the relationship between maximum water equivalent (ground snow load) and elevation. It was found that the relative increase of water equivalent with elevation (ie. the slope of the water equivalent plotted against elevation) could be defined very well for larger regions with similar climatic conditions. For a given mountain, ground snow loads could therefore be predicted by extrapolating from water equivalent values at one elevation to another elevation. Plots of the absolute values of water equivalents against elevation for regions of similar climatic conditions could give only approximate values of ground snow loads- for any particular site. Plots of the mean water equivalent and of the 30 year maximum water equivalent plotted against elevation for the measurement locations and for the regions of similar snow conditions are presented. The density of snow at the time of maximum water equivalent was briefly investigated. No correlation of density with elevation was found.

description: This experimental work presents a comparative study on the mechanical behaviour of novel infusible methylmethacrylate matrix (Elium®) composites reinforced with different types of high-performance fibres. A vacuum-assisted resin infusion process was employed to fabricate the laminates using carbon, basalt, Kevlar®, and high molecular weight polyethene (UHMWPE) fibres. Flexural and interlaminar shear properties of the composites were evaluated. Test results revealed that carbon fibre composites had superior flexural strength, stiffness and interlaminar shear stress as compared to the other composites tested. Further, composites containing Kevlar and UHMWPE fibres demonstrated significantly higher flexural strains to failure. Post-testing, specimens were examined using scanning electron microscopy (SEM). Microscopy revealed possible interfacial interaction differences based on the reinforcement fibre type, which was further confirmed by an analytical approach for analysing the flexural behaviour of various types of composites. The sequence of damage progression in specimens was also analysed

description: The relevance of the article is determined by the ever-growing interest in the genre of the historical novel, the desire to restore the lost unity in the world, all the increasing obstacles on the way to it, the tireless inner struggle of the individual. The study reveals the peculiarities of the artistic interpretation and the specifics of the literary-figurative recreation of the Albanian collisions of the late twentieth century on the example of D. Miller's novel "Lessons of Norwegian". In the novel, there is an artistic interpretation of history, the drawing of semantic threads from modernity to the past and vice versa, the combination and interweaving of heterogeneous narrative elements, an organic fusion of history, mythology and modernity. The writer revealed the dark secrets of history and the human soul, expressed the harsh truth about the war and about ourselves.

description: Biologists have long observed periodic-like oxygen consumption oscillations in yeast populations under certain conditions and several unsatisfactory explanations for this phenomenon have been proposed. These "autonomous oscillations" have often appeared with periods that are nearly integer divisors of the calculated doubling time of the culture. We hypothesize that these oscillations could be caused by a weak form of cell cycle synchronization that we call clustering. We develop some novel ordinary differential equation models of the cell cycle. For these models, and for random and stochastic perturbations, we give both rigorous proofs and simulations showing that both positive and negative growth rate feedback within the cell cycle are possible agents that can cause clustering of populations within the cell cycle. It occurs for a variety of models and for a broad selection of parameter values. These results suggest that the clustering phenomenon is robust and is likely to be observed in nature. Since there are necessarily an integer number of clusters, clustering would lead to periodic-like behavior with periods that are nearly integer divisors of the period of the cell cycle.

PARTICULARITIES OF TIME PERSPECTIVE AND THE SEARCH FOR MEANING

description: The article analyzes long-term studies of the optimal perspective profile among adolescents, young men, individuals of middle and late adulthood, different sexes, and professional activities. It is stated that the presence of an optimal perspective profile has not been confirmed: it is difficult to imagine people with different types of temperament, age, and individual experience having the same meanings and values in relation to the optimal time perspective, regardless of its consistency and balance. It has been demonstrated that in adolescence, in an unbal-anced profile the hedonistic present is expressed on a middle-high level, the search for the meaning of life is called "a decrease of anxiety and guilt by means of entertainment." It is shown that in early adulthood, the search for meaning is defined as “confusion” or “abashment” due to lack of a global goal, avoidance of disturbing information in the present, replacing it with illusions and entertainment, abandoning one's own desires under the pressure of sociocultural stereotypes. It is stated that the experience of living through difficult situations in life increases, during which crises are lost and meanings are born, the life resource decreases, but the presence of a goal at the age of 40+ motivates a person for action and activity. In middle adulthood, the search for meaning is called "to have and to achieve." It is shown that in late adulthood, a high or medium level of time perspectives expressiveness "Negative past" and "Fatalistic present" or "Future" is present, depending on the person's activity. The meaning of life could be called "despair" or "protection", respectively. It is assumed that the lack of connectivity and the optimal balance between the past present future does not reduce adaptive functions, but, on the contrary, works as a defense mechanism helping a person to find meaning.
Effects of disorder upon transport and Anderson Localization in a finite, two dimensional Bose gas

description: Anderson localization in a two-dimensional ultracold Bose-gas has been demonstrated experimentally. Atoms were released within a dumbbell-shaped optical trap, where the channel of variable aspect ratio provided the only path for particles to travel between source and drain reservoirs. This channel can be populated with columnar (repulsive) optical potential spikes of square cross section with arbitrary pattern. These spikes constitute impurities, the scattering centres for the otherwise free propagation of the particles. This geometry does not allow for classical potential trapping which can be hard to exclude in other experimental setups. Here we add further theoretical evidence for Anderson localization in this system by comparing the transport processes within a regular and a random pattern of impurities. It is demonstrated that the transport within randomly distributed impurities is suppressed and the corresponding localization length becomes shorter than the channel length. However, if an equal density of impurities are distributed in a regular manner, the transport is only modestly disturbed. This observation corroborates the conclusions of the experimental observation: the localization is indeed attributed to the disorder. Beyond analysing the density distribution and the localization length, we also calculate a quantum `impedance' exhibiting qualitatively different behaviour for regular and random impurity patterns.

description: Stars in multiple systems offer a unique opportunity to learn about stellar formation and evolution. As they settle down into stable configurations, multiple systems occur in a variety of hierarchies and a wide range of separations between the components. We examine 11 known and 11 newly discovered multiple systems including at least one M dwarf with the latest astrometric data from Gaia Early Data Release 3 (EDR3). We find that the individual components of systems at very wide separations are often multiple systems themselves.

The method was validated using a variety of chemical exchange phantoms and an in-vivo mouse brain at 9.4T. Results: The acquisition times for AutoCEST optimized schedules ranged from 35-71s, with a quantitative image reconstruction time of only 29 ms. The resulting exchangeable proton concentration maps for the phantoms were in good agreement with the known solute concentrations for AutoCEST sequences (mean absolute error = 2.42 mM; Pearson's r=0.992 , p$

description: Two-dimensional materials composed of transition metal carbides and nitrides (MXenes) are poised to revolutionize energy conversion and storage. In this work, we used density functional theory (DFT) to investigate adsorption of Mg and Na adatoms on five M$_{2}$CS$_{2}$ monolayers (where M= Mo, Nb, Ti, V, Zr) for battery applications. We assessed the stability of the adatom (i.e. Na and Mg)-monolayer systems by calculating adsorption and formation energies, as well as voltages as a function of surface coverage. For instance, we found that Mo$_{2}$CS$_{2}$ cannot support a full layer of Na nor even a single Mg atom. Na and Mg exhibit the strongest binding on Zr$_{2}$CS$_{2}$, followed by Ti$_{2}$CS$_{2}$, Nb$_{2}$CS$_{2}$ and V$_{2}$CS$_{2}$. Using the nudged elastic band method (NEB) we computed promising diffusion barriers for both dilute and nearly-full ion surface coverage cases. In the dilute ion adsorption case, a single Mg and Na atom on Ti$_{2}$CS$_{2}$ experience $\sim$0.47 eV and $\sim$0.10 eV diffusion barriers between the lowest energy sites, respectively. For a nearly full surface coverage, a Na ion moving on Ti$_{2}$CS$_{2}$ experiences a $\sim$0.33 eV energy barrier, implying a concentration dependent diffusion barrier. Our molecular dynamics results indicate that three (one) layers (layer) of Mg (Na) ion on both surfaces of Ti$_{2}$CS$_{2}$ remain stable at T=300 K. While, according to voltage calculations, Zr$_{2}$CS$_{2}$ can store Na up to three atomic layers, our MD simulations predict that the outermost layers detach from Zr$_{2}$CS$_{2}$ monolayer due to weak interaction between Na ions and the monolayer. This suggests that MD simulations are essential to confirming the stability of an ion-electrode system - an insight that is mostly absence in previous studies.

description: In some problem spaces, the high cost of obtaining ground truth labels necessitates use of lower quality reference datasets. It is difficult to benchmark model performance using these datasets, as evaluation results may be biased. We propose a supplement to using reference labels, which we call an approximate ground truth refinement (AGTR). Using an AGTR, we prove that bounds on specific metrics used to evaluate clustering algorithms and multi-class classifiers can be computed without reference labels. We also introduce a procedure that uses an AGTR to identify inaccurate evaluation results produced from datasets of dubious quality. Creating an AGTR requires domain knowledge, and malware family classification is a task with robust domain knowledge approaches that support the construction of an AGTR. We demonstrate our AGTR evaluation framework by applying it to a popular malware labeling tool to diagnose over-fitting in prior testing and evaluate changes whose impact could not be meaningfully quantified under previous data.

description: Part of a collection of correspondence from Kathleen Raine to Robin Skelton. Skelton was a British poet, academic, anthologist, and practicing Wiccan. He taught at Manchester University before emigrating to Canada in 1963, where he taught creative writing at the University of Victoria and started the literary magazine The Malahat Review. Also included are some letters to Skelton’s wife Sylvia, and his daughters. Spanning close to forty-five years, the correspondence discusses poetry, writing, and philosophy; particularly Platonism and Neoplatonism. Raine often refers to the writings of William Blake and W. B. Yeats. Many letters also mention contemporary literary figures at the time including: Herbert Read, Peter Russell, Liam Miller, and Thurairajah Tambimuttu. In this letter, Raine discusses interpreting Wordsworth.

Dark Matter in the MSSM Golden Region

description: Dark matter is examined within the ``golden region'' of the Minimal Supersymmetric Standard Model. This region satisfies experimental constraints, including a lower bound on the Higgs mass of 114 GeV, and minimizes fine-tuning of the Z boson mass. Here we impose additional constraints (particularly due to experimental bounds on $b\to s γ$). Then we find the properties of the Dark Matter in this region. Neutralinos with a relic density that provides the amount of dark matter required by cosmological data are shown to consist of a predominant gaugino (rather than higgsino) fraction. In addition, the U(1)$_Y$ gaugino mass parameter must satisfy $M_1 < 300$ GeV.

A Bayesian technique of flood frequency estimation with application to the Yukon Territory
Creators: name: Chan, Andrew
Publisher: name: University of British Columbia
Year: 2010

description: Some presently available methods of flood frequency estimation require considerable recorded peak flow data. Others generate large quantities of dubious artificial data for analysis. These methods are very difficult to apply to sparse data regions, instead, the main approach is to use regional methods. These have met with some success but are limited as not much of the available data is utilized. This thesis presents a method of estimating flood frequencies for sparse to abundant data regions. Several types of typically available data as well as subjectively assessed data are incorporated. Uncertainty in the data is taken into account and reflected in the conservatism of the results. The method is developed with regard to its subsequent application to the Yukon Territory. The assumption of natural peak flows following some mathematically describable distribution, forms; the basis of the method. Bayes' Theorem is applied to probabilistically determine the most probable distributions given the observed data. The theory, assumptions, method of solution and hydrologic considerations are discussed before the results of an example basin are presented. From the results, it can be concluded that the method gives reasonable results, in accord with given data, and that it is a logical working procedure to apply in practice.

description: We address the task of modeling soft X-ray and optical light curves of X-ray novae in the high/soft state. The analytic model of viscous evolution of an externally truncated accretion α-disk is used. Relativistic effects near a Kerr black hole and self-irradiation of an accretion disk are taken into account. The model is applied to the outbursts of X-ray nova Monocerotis 1975 (A 0620-00) and X-ray nova Muscae 1991 (GRS 1124-68). Comparison of observational data with the model yields constraints on the angular momentum (the Kerr parameter) of the black holes in A 0620-00 and GRS 1124-68: 0.3-0.6 and \leq 0.4, and on the viscosity parameter αof the disks: 0.7-0.95 and 0.55-0.75. We also conclude that the accretion disks should have an effective geometrical thickness 1.5-2 times greater than the theoretical value of the distance between the photometric layers.

description: We study the intrinsic computational power of correlations exploited in measurement-based quantum computation. By defining a general framework the meaning of the computational power of correlations is made precise. This leads to a notion of resource states for measurement-based \textit{classical} computation. Surprisingly, the Greenberger-Horne-Zeilinger and Clauser-Horne-Shimony-Holt problems emerge as optimal examples. Our work exposes an intriguing relationship between the violation of local realistic models and the computational power of entangled resource states.
