Study of CP Symmetry Violation in the Charmonium-K*(892) Channel By a Complete Time Dependent Angular Analysis (BaBar Experiment)

This thesis presents the full-angular time-dependent analysis of the vector-vector channel B{sub d}{sup 0} {yields} J/{psi}(K{sub S}{sup 0}{pi}{sup 0})*{sup 0}. After a review of the CP violation in the B meson system, the phenomenology of the charmonium-K*(892) channels is exposed. The method for the measurement of the transversity amplitudes of the B {yields} J/{psi}K*(892), based on a pseudo-likelihood method, is then exposed. The results from a 81.9 fb{sup -1} of collected data by the BABAR detector at the {Upsilon}(4S) resonance peak are |A{sub 0}|{sup 2} = 0.565 {+-} 0.011 {+-} 0.004, |A{sub {parallel}}|{sup 2} = 0.206 {+-} 0.016 {+-} 0.007, |A{sub {perpendicular}}|{sup 2} = 0.228 {+-} 0.016 {+-} 0.007, {delta}{sub {parallel}} = -2.766 {+-} 0.105 {+-} 0.040 and {delta}{sub {perpendicular}} = 2.935 {+-} 0.067 {+-} 0.040. Note that ({delta}{sub {parallel}}, {delta}{sub {perpendicular}}) {yields} (-{delta}{sub {parallel}}, {pi} - {delta}{sub {perpendicular}}) is also a solution. The strong phases {delta}{sub {parallel}} and {delta}{sub {perpendicular}} are at {approx}> 3{sigma} from {+-}{pi}, signing the presence of final state interactions and the breakdown of the factorization hypothesis. The forward-backward analysis of the K{pi} mass spectrum revealed the presence of a coherent S-wave interfering with the K*(892). It is the first evidence of this wave in the …

Mariama Bâ: un féminisme né à l'intersection de deux cultures. (open access)

Mariama Bâ: un féminisme né à l'intersection de deux cultures.

Many critics consider Mariama Bâ as a feminist writer, but the reader of her two novels might wonder what characterizes her work as such. Therefore, the aim of each chapter, in order of appearance, is to analyze first the genres, then the elements of African tradition and Western modernity, the characters of both works and the themes of the novels, with the intention of defining the author's feminism, which takes its source in dichotomies, paradoxes and contradictions. In order to expose the author's point of view on the condition of women, it appears important to situate the diegesis in its context. Also, the study is supported by references on the Senegalese culture, by genres, narrative and feminist theories and by critiques on the work itself.

Biodiversité: Quelle Recherche Dans 15 Ans?: Enjeux, Chercheurs, Contextes

Proceedings of a meeting of the French Institute of Biodiversity (IFB), setting a course of research for the next fifteen years. The IFB, composed of government agencies, research organizations, and NGOs, is a scientific interest group promoting scientific research in biodiversity. The IFB is devoted to coordinating research on biodiversity in all natural and social sciences, to promoting biodiversity research at the national, European, and international levels, and to disseminating knowledge and providing educational outreach to the general public.
