Astrophysical point source search with the ANTARES neutrino telescope

The ANTARES neutrino telescope is installed at a depth of 2.5 km of the Mediterranean Sea and consists of a three-dimensional array of 885 photomultipliers arranged on twelve detector lines. The prime objective is to detect high-energy neutrinos from extraterrestrial origin. Relativistic muons emerging from charged-current muon neutrino interactions in the detector surroundings produce a cone of Cerenkov light which allows the reconstruction of the original neutrino direction. The collaboration has implemented different methods to search for neutrino point sources in the data collected since 2007. Results obtained with these methods as well as the sensitivity of the telescope are presented.Comment: 1 page, 1 figur

“Their Image of Me”: A Phenomenological Study of Professional Dress Choices of Female Professors

In recent years, scholarly attention to professional dress as a form of nonverbal communication has faded into the background. However, I believe professional dress is an important area of study, considering the changing conditions in the world of work. Therefore, I decided to conduct this phenomenological study of the dress choices of female professors at a small, liberal arts college to discover what professional dress did for them internally and professionally. The analysis of the data suggests that these women try to use dress to represent themselves as who they are internally, without losing sight of their image as a professor, academic, and cultural member. Dress, for them, is a means of controlling and shaping who they view themselves to be into an appropriate external image of who they must be

Observation of Anisotropy in the Arrival Direction Distribution of Cosmic Rays above TeV Energies with Icecube

Between May 2009 and May 2010, the IceCube neutrino detector recorded 32 billion of atmospheric muons generated in air showers produced by cosmic rays in the TeV energy range. With such high statistics sample it is possible to observe, for the first time in the southern hemisphere, an energy dependence in the Galactic cosmic ray anisotropy up to a few hundred TeV. This study shows that the same large-scale anisotropy observed at median energies around 20 TeV is not present at 400 TeV; the anisotropy observed at 400 TeV shows substantial differences with respect to that at lower energy. In addition to the large-scale features observed at 20 TeV in the form of strong dipole and quadrupole moments, the data include several localized regions of excess and deficit on scales between 10{\degree} to 30{\degree}. The features observed at both large and small scale are statistically significant, but their origin is currently unknown.Comment: Proceedings of Rencontres de Blois 201

The Masculine Sea and the Impossibility of Awakening in Chopin's the Awakening

Kate Chopin has a firm place in American women's writing. A persistent theme in her works is said to be women's emotional liberation. The Awakening (1899) as a feminist novel is no exception. In the novel, Edna's inner voice and desire for escape from a male-dominated society awaken in her. Edna's suicide has been interpreted as her victory over the society however, this study argues that the idea of female defeat has been ignored to a great extent the main reason for which is the ignorance or a misreading of sea imagery. The sea of the novel that dissolves Edna is a signifier of male society and language signifying Edna's failure to find a place within the male dialogue of the society. Extra-marital relationships with Alcee or Robert are not promising, for the climax of such relationships is no more than the old requirement of becoming the good wife and mother that the society prescribes to women. By her ultimate suicidal choice, Edna determines to find a voice and be seen but is totally perished instead to prove that women cannot speak. This study intends to argue and conclude that Chopin had this Kristevaesque belief that the male socio-cultural formation does not let women experience freedom. A new interpretation of the sea as a patriarchal element is offered which makes Edna's drowning a total defeat rather than victory as suggested by many critics

Monte Carlo Computation of Spectral Density Function in Real-Time Scalar Field Theory

Non-perturbative study of "real-time" field theories is difficult due to the sign problem. We use Bold Schwinger-Dyson (SD) equations to study the real-time $\phi^4$ theory in $d=4$ beyond the perturbative regime. Combining SD equations in a particular way, we derive a non-linear integral equation for the two-point function. Then we introduce a new method by which one can analytically perform the momentum part of loop integrals in this equation. The price we must pay for such simplification is to numerically solve a non-linear integral equation for the spectral density function. Using Bold diagrammatic Monte Carlo method we find non-perturbative spectral function of theory and compare it with the one obtained from perturbation theory. At the end we utilize our Monte Carlo result to find the full vertex function as the basis for the computation of real-time scattering amplitudes.Comment: 25 pages, 4 figure

Polarized and Unpolarized Lepton Pair Forward-backward Asymmetries in B‾→K‾0∗(1430)ℓ+ℓ−\overline{B}\rightarrow \overline{K}_{0}^{*}(1430) \ell^+\ell^- and B‾→K‾ℓ+ℓ−\overline{B}\rightarrow \overline{K} \ell^+\ell^- Decays in Two Higgs Doublet Model

In this paper we shall focus on the effects of concrete models such as SM and Model III of 2HDM on the polarized and unpolarized forward-backward asymmetries of $\overline{B}\rightarrow \overline{K}_0^{*}(1430) \ell^+\ell^-$ and $\overline{B}\rightarrow \overline{K} \ell^+\ell^-$ decays. The obtained results of these decay modes are compared to each other. Also, we obtain the minimum required number of events for detecting each asymmetry and compare them with the number of produced $B\bar{B}$ pairs at the LHC or supposed to be produced at the Super-LHC. At the end, we conclude that the study of these asymmetries for $\overline{B}\rightarrow \overline{K}_0^*(1430) \ell^+\ell^-$ and $\overline{B}\rightarrow \overline{K} \ell^+\ell^-$ processes are very effective tools for establishing new physics in the future B-physics experiments

Strong coupling constant of hb_{b} vector to the pseudoscalar and vector BcB_{c} mesons in QCD sum rules

The strong coupling constant g$_{h_{b}B_{c}^{PS}B_{c}^{V}}$ is calculated using the three-point QCD sum rules method. We use correlation functions to obtain these strong coupling constants with contributions of both B$_{c}^{PS}$ and B$_{c}^{V}$mesons as off-shell states. The contributions of two gluon condensates as a radiative correction are considered. The results show that g$_{h_{b}B_{c}^{PS}B_{c}^{V}}=8.80\pm 2.84 GeV^{-1}$and g$_{h_{b}B_{c}^{V} B_{c}^{PS}}=9.34\pm 3.12 GeV^{-1}$ in the $B_{c}^{PS}$ and $B_{c}^{V}$ off-shell state, respectively.Comment: 9 pages, 4 figure
