An Angular Distribution Analysis of Λ B Decays *
A study of the angular distributions of the processes Λ b → ΛV (1 −) with V (J/Ψ, ρ 0) is performed. Emphasis is put on the initial Λ b polarization and the polarization density-matrices are derived to perform tests of both Time-Reversal (TR) and CP violation. 1. Λ b DECAY AND INTERMEDIATE RESONANCE ANALYSIS In the collisions, pp → Λ b + X, the Λ b is produced with a transverse polarization in ...
متن کاملAngular Distribution of Leptons from Top-Quark Decays
Angular distribution of the secondary lepton in top-quark production followed by subsequent semi-leptonic decay is studied assuming general top-quark couplings. It is shown that the distribution does not depend on any possible anomalous tbW couplings and is determined only by the standard V −A decay vertex for any production mechanism if certain well-justified conditions are satisfied. PACS: 13...
متن کاملan infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
15 صفحه اولAngular Distribution and CP Asymmetries in the Decays B̄ →
The short-distance Hamiltonian describing b → s(d)e−e+ in the standard model is used to obtain the decay spectrum of B̄ → K−π+e−e+ and B̄ → π−π+e−e+, assuming the Kπ and ππ systems to be the decay products of K∗ and ρ respectively. Specific features calculated are (i) angular distribution of K− (or π−) in the K−π+ (or π−π+) centre-of-mass (c.m.) frame; (ii) angular ∗E-mail address: krueger@gtae3....
