Application of the Faddeev-Jackiw formalism to the gauged WZW model
The two-flavor Wess-Zumino model coupled to electromagnetism is treated as a
constraint system using the Faddeev-Jackiw method. Expanding into series of
powers of the pion fields and keeping terms up to second and third order we
obtain Coulomb- gauge Lagrangeans containing non-local terms.Comment: 10 pages, LaTe
Resummation of Running Coupling Effects in Semileptonic B Meson Decays and Extraction of
We present a determination of from semileptonic B decays that
includes resummation of supposedly large perturbative corrections, originating
from the running of the strong coupling. We argue that the low value of the BLM
scale found previously for inclusive decays is a manifestation of the
renormalon divergence of the perturbative series starting already in third
order. A reliable determination of from inclusive decays is possible
if one either uses a short-distance b quark mass or eliminates all unphysical
mass parameters in terms of measured observables, such that all infra-red
contributions of order cancel explicitly. We find that using the
running mass significantly reduces the perturbative
coefficients already in low orders. For a semileptonic branching ratio of
we obtain from
inclusive decays, in good agreement with the value extracted from exclusive
decays.Comment: 37 pages + 4 figures, final version accepted for publication in Phys.

Gender portrayals revisited: searching for explicit and implicit stereotypes in Cypriot magazine advertisements
The study pursues a line of inquiry into contemporary gender stereotypes drawn from print advertisements in Cyprus. The investigation of implicit modes of stereotyping suggested by Goffman across explicit gender roles yield novel and interesting insights that broaden existing knowledge on male and female advertising depictions. Through a content analysis of 3.729 characters, the study reveals the existence of gender cliches in Cypriot magazine advertisements. Neither male nor female evolving roles are adequately reflected in advertisements, as men tend to be portrayed in traditional masculine stereotypes while women lean towards decorative portrayals. Implicit stereotyping is more likely to suggest the subordination and lower status of women compared to men. The study indicates that advertising in Cyprus reinforces the diffusion of hostile sexism by the underrepresentation of professional women and their commonplace portrayal in body revealing attires. At the same time, the high proportion of women's implicit subordination signifies benevolent sexism. The distorted representation of both genders raises key public policy concerns, as diminishing portrayals hold sway upon men's and women's psychological well-being and professional development
Ground-state configuration of neutron-rich Aluminum isotopes through Coulomb breakup
Neutron-rich 34,35Al isotopes have been studied through Coulomb excitation using LAND-FRS setup at GSI, Darmstadt. The method of invariant mass analysis has been used to reconstruct the excitation energy of the nucleus prior to decay. Comparison of experimental CD cross-section with direct breakup model calculation with neutron in p3/2 orbital favours 34Al(g.s) - νp3/2 as ground state configuration of 35Al. But ground state configuration of 34Al is complicated as evident from γ-ray spectra of 33Al after Coulomb breakup of 34Al. \ua9 Owned by the authors, published by EDP Sciences, 2014
