Covariant Light-Front Approach for s-wave and p-wave Mesons
Chun-Khiang Chua
We study the decay constants and form factors of the ground-state s-wave and low-lying p-wave mesons within a covariant light-front approach. Numerical results of the B to D** tran…
Covariant Light-Front Approach for s-wave and p-wave Mesons: Its Application to Decay Constants and Form Factors
Hai-Yang Cheng, Chun-Khiang Chua, Chien-Wen Hwang
We study the decay constants and form factors of the ground-state s-wave and low-lying p-wave mesons within a covariant light-front approach. Numerical results of the form factors…
and CP Asymmetries from Supersymmetric Right-handed Flavor Mixing: Implications for Heavy Quark Phenomenology
Chun-Khiang Chua, Wei-Shu Hou, Makiko Nagashima
Two recent experimental developments, when combined, may have far reaching implications. , if confirmed, would imply large - mixing, a new CP phase, and right-h…
High energy tau neutrinos: production, propagation and prospects of observations
H. Athar, Jie-Jun Tseng, Guey-Lin Lin
High energy tau neutrinos with energy greater than several thousands of GeV may be produced in some astrophysical sites. A summary of the intrinsic high energy tau neutrino flux es…
Weak phases from topological-amplitude parametrization
Yeo-Yie Charng, Hsiang-nan Li
We propose a parametrization for two-body nonleptonic meson decays, in which the various topologies of amplitudes are counted in terms of powers of the Wolfenstein parameter $λ…
Hadronic B Decays Involving Even Parity Charmed Mesons
Hai-Yang Cheng
Hadronic B decays containing an parity-even charmed meson in the final state are studied. Specifically we focus on the Cabibbo-allowed decays $\bar B\to D^{**} π(ρ), D^{**}\bar D_s…
