description: The two photon decay width of the neutral pion is analyzed within the combined framework of Chiral Perturbation Theory and the 1/Nc expansion up to order p^6 and p^4 times 1/Nc in the decay amplitude. The eta' is explicitly included in the analysis. It is found that the decay width is enhanced by about 4.5% due to the isospin-breaking induced mixing of the pure U(3) states. This effect, which is of leading order in the low energy expansion, is shown to persist nearly unchanged at next to leading order. The chief prediction for the width with its estimated uncertainty is 8.10+-0.08 eV. This prediction at the 1% level makes the upcomming precision measurement of the decay width even more urgent. Observations on the eta and eta' can also be made, especially about their mixing, which is shown to be significantly affected by next to leading order corrections.

Collapse of a Rotating Supermassive Star to a Supermassive Black Hole: Analytic Determination of the Black Hole Mass and Spin

description: The collapse of a uniformaly rotating, supermassive star (SMS) to a supermassive black hole (SMBH) has been followed recently by means of hydrodynamic simulations in full general relativity. The initial SMS of arbitrary mass M in these simulations rotates uniformly at the mass--shedding limit and is marginally unstable to radial collapse. The final black hole has mass M_h/M = 0.9 and and spin J_h/M_h^2 = 0.75, approximately. The remaining mass goes into a disk of mass M_disk/M = 0.1, also approximately. Here we show that these black hole and disk parameters can be calculated analytically from the initial stellar density and angular momentum distribution. The analytic calculation thereby corroborates and provides a simple physical explanation for the computational discovery that SMS collapse inevitably terminates in the simultaneous formation of a SMBH and a rather substantial ambient disk. This disk arises even though the total spin of the progenitor star, J/M^2 = 0.97, is safely below the Kerr limit. The calculation performed here applies to any marginally unstable n = 3 polytrope uniformly rotating at the break--up speed, independent of stellar mass or the source of internal pressure. It illustrates how the black hole and disk parameters can be determined for the collapse of other types of stars with different initial density and rotation profiles.

Investigation of noscale supersymmetry breaking models with a gauged U(1)_{B-L} symmetry

description: Noscale supersymmetry (SUSY) breaking model is investigated in the minimal extension of the minimal supersymmetric standard model (MSSM) with a gauged U(1)_{B-L} symmetry. We specifically consider a unification-inspired model with the gauge groups SU(3)_{C} \times SU(2)_{L} \times U(1)_Y \times U(1)_{B-L} \subset SU(5) \times U(1)_{5} for illustration. While the noscale boundary condition at the grand unification scale (M_{G}\simeq 2\times 10^{16} GeV) in the MSSM is not consistent with phenomenological constraints, we show that it is if the gaugino of the U(1)_{5} multiplet is several times heavier than the gauginos of the MSSM. However, if SU(5) \times U(1)_{5} is further embedded in a larger simple group, e.g. SO(10), the noscale boundary condition at M_{G} is inconsistent with phenomenological constraints. If we relax the noscale boundary condition and allow non-zero soft scalar masses for the Higgs fields which spontaneously break the U(1)_{5} symmetry, the resultant spectrum of SUSY particles becomes consistent with all the phenomenological constraints, even if we impose the GUT relation on the gauge coupling and the gaugino mass of the U(1)_{5}. In this case, the SUSY CP problem is also solved, since the condition Bμ=0 at the boundary can be imposed consistently with the electroweak symmetry breaking.

Kaluza-Klein gravitino production with a single photon at e^+ e^- colliders

description: In a supersymmetric large extra dimension scenario, the production of Kaluza-Klein gravitinos accompanied by a photino at e^+ e^- colliders is studied. We assume that a bulk supersymmetry is softly broken on our brane such that the low-energy theory resembles the MSSM. Low energy supersymmetry breaking is further assumed as in GMSB, leading to sub-eV mass shift in each KK mode of the gravitino from the corresponding graviton KK mode. Since the photino decays within a detector due to its sufficiently large inclusive decay rate into a photon and a gravitino, the process e^+ e^- -> photino + gravitino yields single photon events with missing energy. Even if the total cross section can be substantial at sqrt(s)=500 GeV, the KK graviton background of e^+ e^- -> photon + graviton is kinematically advantageous and thus much larger. It is shown that the observable, sigma(e^-_L)-sigma(e^-_R), can completely eliminate the KK graviton background but retain most of the KK gravitino signal, which provides a unique and robust method to probe the supersymmetric bulk.

description: Osmotic treatment (OT) is a process applied for drying of fruits and vegetables where the hypertonic solution is osmotic medium. White cabbage (cultivar „Futoški“) shelf-life analysis was conducted after OT in three different hypertonic solutions: a mixture of commercial sucrose and NaCl (S1), a mixture of S1 and molasses in the ratio 1:1 (S2) and. pure sugar beet molasses (85.4% dry matter) (S3). After the OT, cabbage samples were packed in high barrier bags in the modified atmosphere packaging (MAP). The composition of two mix-tures of used gas (40:60/CO2:N2 and 80:20/CO2:N2) was imported into bags. The samples were analysed for L-ascorbic acid content, pH, acidity and a total number of microorganisms and sensorial attributes during 90 days of storage in a refrigerator at 4-8 °C in defined time intervals. During the 90-day storage in the MAP, microbiological analysis showed that the number of microorganisms decreased during the storage in the MAP. The highest retention of ascorbic acid (27.35%) was observed in OT cabbage dehydrated in pure molasses solution and 80:20/CO2:N2 gas mixture after 90 days of storage. Sensory analysis showed that osmodehydrated cabbage for 20 days in S1, and 45 days for OT cabbage in solutions S2 and S3 had acceptable consumable characteristics.

description: The potato is a major vegetable crop around the world, and tuberous hypertrophy is a highly complex developmental process effected by various factors that play central role in potato growth. Tuber growth under hypertrophic conditions is regulated by variations in carbohydrates and endogenous phytohormones. In the present study, we aimed to establish the basis for the enlargement of potato tubers, including changes in the chemical content of factors related to tuber formation and hypertrophy based on phytohormonal regulation, plants height and tuber biomass and other selected attributes. Our results reveal that the application of plant growth regulators such as diniconazole (Din) and prohydrojasmon (PDJ) significantly impact on potato plants growth and yield, including that of tubers. Plants treated with Din and PDJ effectively showed stunted growth and re-duced development but enhance the tuber formation and its weight. Plants treated with Din and PDJ significantly reduced the GAs and ABA accumulation and increase the sucrose level and cause significant increase in tuber development. In conclusion, a higher gibberellin content in potatoes may inhibit tuberization. Diniconazole and PDJ treatment reduced gibberellin accumulation, which in turn regu-lated abscisic acid content, demonstrating that the abscisic acid content mostly increased as gibberellin content decreased, and thereby promoting tuberization.

description: We report a strong Kondo effect (Kondo temperature ~ 4K) at high magnetic field in a selective area growth semiconductor quantum dot. The Kondo effect is ascribed to a singlet-triplet transition in the ground state of the dot. At the transition, the low-temperature conductance approaches the unitary limit. Away from the transition, for low bias voltages and temperatures, the conductance is sharply reduced. The observed behavior is compared to predictions for a two-stage Kondo effect in quantum dots coupled to single-channel leads.

A simple two-component description of mass segregation for anisotropic globular clusters

description: As a result of the slow action of two-body encounters, globular clusters develop mass segregation and attain a condition of only partial energy equipartition even in their central, most relaxed regions. Realistic numerical simulations show that, during the process, a radially-biased anisotropy profile slowly builds up, mimicking that resulting from incomplete violent relaxation. Commonly used dynamical models, such as the one-component King models, cannot describe these properties. Here we show that simple two-component models based on a distribution function originally conceived to describe elliptical galaxies, recently truncated and adapted to the context of globular clusters, can describe in detail what is observed in complex and realistic numerical simulations.

description: The article is devoted to the analysis of episodes of public deri­sion of the impostor Til Kolup, who proclaimed himself the emperor Frederick II in 1284-1285 II Staufen (1194-1250) in the Rhine lands of the German Empire - at a time when the former dynasty was ended, and the legitimacy of the new (Habsburg) was yet not indisputable. The author analyses the detailed evidences of two chronicles of the end of the 13 th - the first quarter of the 14 th century (Gesta Henrici Archiepiscopi Trecerensis, Iohannis abbatis Victoriensis Liber centarum historicarum), introducing them into scientific use of our coun­try The author explores how the laugh operates in the political discourse. The paper shows that the laugh in the dramatized performances in the market square of Cologne and Wetzlar accomplished various functions. Besides laughing and deriding, it served as a way of townsfolk’s denial of their loyalty’ to so-called emperor Frederick II and their oath of allegiance to their legal king at the same time. Therefore the laugh was a kind of symbolic communication of power and society, well understood by both sides. The attributes and sets of
carnival (market square, townsfolk, a character of a fool king as a protagonist) were in fact incorporated in the “serious” discourse of politics from the space of humour and laugh. It became an instrument for representation the social and
political attitude of a social group. In summary, it was the figure of impostor that enabled uncovering the mechanism of the usage of laugh and his functions as a political language in the urban culture in the Middle Ages.

description: We provide new very simple and compact expressions for the efficient calculation of gravitational lens optical scalars for Kerr spacetime which are exact along any null geodesic. These new results are obtained recurring to well known results on geodesic motion that exploit obvious and hidden symmetries of Kerr spacetime and contrast with the rather long and cumbersome expressions previously reported in the literature, providing a helpful improvement for the sake of an efficient integration of the geodesic deviation equation on Kerr geometry. We also introduce a prescription for the observer frame which captures a new notion of \emph{center of the black hole} which can be used for any position of the observer, including those near the black hole. We compare the efficient calculation of weak lens optical scalars with the exact equations; finding an excellent agreement.

description: A variety of observations indicate that the universe is dominated by dark energy with negative pressure, one possibility for which is a cosmological constant. If the dark energy is a cosmological constant, a fundamental question is: Why has it become relevant at so late an epoch, making today the only time in the history of the universe at which the cosmological constant is of order the ambient density. We explore an answer to this question drawing on ideas from unimodular gravity, which predicts fluctuations in the cosmological constant, and causal set theory, which predicts the magnitude of these fluctuations. The resulting ansatz yields a fluctuating cosmological ``constant'' which is always of order the ambient density.

We expect these new solutions to provide a more realistic description of black hole disks than the slim disk model. We are presenting a disk solution for a non-spinning black hole at a sub-Eddington mass accretion rate, $\dot M=0.6\,\dot M_{\rm Edd}$. By the density scale-height measure the disk appears to be thin, having a high density core near the equatorial plane of height $h_ρ \sim 0.1 \,r$, but most of the inflow occurs through a highly advective, turbulent, optically thick, Keplerian region that sandwiches the core and has a substantial geometrical thickness comparable to the radius, $H \sim r$. The accreting fluid is supported above the midplane in large part by the magnetic field, with the gas and radiation to magnetic pressure ratio $β\sim 1$, this makes the disk thermally stable, even though the radiation pressure strongly dominates over gas pressure. A significant part of the radiation emerging from the disk is captured by the black hole, so the disk is less luminous than a thin disk would be at the same accretion rate.

description: The edge and bulk structure of Landau levels (LLs) in a wide channel at the $ ν=1$ quantum Hall regime is calculated for not-too-low temperatures, $\hbar ω_{c} \gg k_{B}T\gg \hbar v_{g}/2\ell_{0}$, where $v_{g}$ is the group velocity of the edge states and $\ell_{0}=\sqrt{\hbar c/|e|B}$ is the magnetic length. Edge-states correlations essentially modify the spatial behavior of the lowest spin-up LL, which is occupied, compared to the lowest spin-down LL, which is empty. The influence of many-body interactions on the spatially inhomogeneous spin-splitting between the two lowest LLs is studied within the generalized local density approximation. Temperature effects on the enhanced spin-splitting, the position of the Fermi level within the exchange enhanced gap and the renormalization of edge-states group velocity by edge states screening are considered. It is shown that the maximum activation energy $G$ in the bulk of the channel is determined by the gap between the Fermi level and the bottom of the spin-down LL, because the gap between the Fermi level and the spin-up LL is much larger. For the maximum value of $G$, it is shown that the renormalized group velocity $v_{g}\propto T$ for $T\to 0$ and, in particular, the condition of not-too-low $T$ can be satisfied for $4.2\agt T\agt0.3$ K. In other words, the regime of not-too-low temperatures regime can be achieved even for rather low $T$.

description: The Z-burst mechanism invoked to explain ultra-high energy cosmic rays is severely constrained by measurements of the cosmic gamma-ray background by EGRET. We discuss the case of optically thick sources and show that jets and hot spots of active galaxies cannot provide the optical depth required to suppress the photon flux. Other extragalactic accelerators (AGN cores and sites of gamma ray bursts), if they are optically thick, could be tested by future measurements of the secondary neutrino flux.

description: La fouille réalisée sur la commune de Berru (Marne) au lieu-dit « La Maladrerie », se situe au pied du versant nord du mont de Berru, butte témoin du plateau tertiaire d’Île de France. Si le secteur est réputé pour ses découvertes lithiques préhistoriques, il l’est surtout pour ses nécropoles du début du second âge du Fer. Ces anciennes fouilles de la fin du XIXe et du début du XXe siècle ont contribué à définir la chronologie de La Tène ancienne en France septentrionale, ainsi que le groupe social singularisé par les tombes à char. La tombe à char du lieu-dit « le Terrage » est un des exemples les plus anciens du groupe 1 des tombes à chars, attribuée à la fin du Ve et au début du IVe siècle avant notre ère et connue pour avoir livré le casque de « type Berru » : un casque en bronze martelé orné de corail et de palmettes gréco-étrusques gravées, caractéristiques du Premier style de l’art celtique.

description: We study the direct CP asymmetry of the decays b -> s gamma and b -> d gamma in the context of two models: i) a supersymmetric (SUSY) model with unconstrained SUSY phases, and ii) a model with a single generation of vector quarks. In both the above models we show that b -> d gamma can sizeably influence the combined asymmetry (i.e. that of a sample containing both b -> s gamma and b -> d gamma), and in case (ii) may in fact be the dominant contribution.

description: Groundwater in many States has become contaminated, raising concerns about risks to human health. Farm chemicals are a major source of contamination. Congress has introduced several bills to protect groundwater, and some States have adopted groundwater protection strategies. Rural areas, relying heavily on private wells, may be at the most risk from contaminated groundwater, yet would likely receive less protection than urban areas under proposed strategies permitting different levels of protection. Programs to protect farm and rural income while meeting water quality goals are likely to receive the most enthusiasm in rural areas.

description: Rate-distortion (RD) theory is at the heart of lossy data compression. Here we aim to model the generalized RD (GRD) trade-off between the visual quality of a compressed video and its encoding profiles (e.g., bitrate and spatial resolution). We first define the theoretical functional space $\mathcal{W}$ of the GRD function by analyzing its mathematical properties.We show that $\mathcal{W}$ is a convex set in a Hilbert space, inspiring a computational model of the GRD function, and a method of estimating model parameters from sparse measurements. To demonstrate the feasibility of our idea, we collect a large-scale database of real-world GRD functions, which turn out to live in a low-dimensional subspace of $\mathcal{W}$. Combining the GRD reconstruction framework and the learned low-dimensional space, we create a low-parameter eigen GRD method to accurately estimate the GRD function of a source video content from only a few queries. Experimental results on the database show that the learned GRD method significantly outperforms state-of-the-art empirical RD estimation methods both in accuracy and efficiency. Last, we demonstrate the promise of the proposed model in video codec comparison.

description: We develop a renormalization method for calculating the electronic structure of single and double quantum dots under intense ac fields. The nanostructures are emulated by lattice models with a clear continuum limit of the effective-mass and single-particle approximations. The coupling to the ac field is treated non-perturbatively by means of the Floquet Hamiltonian. The renormalization approach allows the study of dressed states of the nanoscopic system with realistic geometries as well arbitrary strong ac fields. We give examples of a single quantum dot, emphasizing the analysis of the effective-mass limit for lattice models, and double-dot structures, where we discuss the limit of the well used two-level approximation.

description: We present a coordinated study of the paramagnetic-to-antiferromagnetic, rhombohedral-to-monoclinic, and metal-to-insulator transitions in thin-film specimens of the classic Mott insulator V$_2$O$_3$ using low-energy muon spin relaxation, x-ray diffraction, and nanoscale-resolved near-field infrared spectroscopic techniques. The measurements provide a detailed characterization of the thermal evolution of the magnetic, structural, and electronic phase transitions occurring in a wide temperature range, including quantitative measurements of the high- and low-temperature phase fractions for each transition. The results reveal a stable coexistence of the high- and low-temperature phases over a broad temperature range throughout the transition. Careful comparison of temperature dependence of the different measurements, calibrated by the resistance of the sample, demonstrates that the electronic, magnetic, and structural degrees of freedom remain tightly coupled to each other during the transition process. We also find evidence for antiferromagnetic fluctuations in the vicinity of the phase transition, highlighting the important role of the magnetic degree of freedom in the metal-insulator transition.

description: My research sought to determine if gendered roles or patterns exist within mixed gender groups carrying out structured
 and informal group-work in Irish higher education, with a particular focus on the Sciences. A key step of the research was to understand these patterns so as to allow a series of considerations for practice to be developed based on key stakeholder input, including the student and staff perspective. The ultimate aim of my research was to develop tangible, actionable and evidenced-based considerations for staff and students to foster a more equitable learning space and
 to enhance group work across all Irish higher education institutions. Although the focus is on Science-based group work, these considerations will have reach and transferability across institutions and disciplines.
