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…
Charmless Two-body Baryonic B Decays
Chun-Khiang Chua
We study charmless two-body baryonic B decays in a diagramatic approach. Relations on decay amplitudes are obtained. In general there are more than one tree and more than one pengu…
Accounting for Slow J/psi from B Decay
Chun-Khiang Chua, Wei-Shu Hou, Gwo-Guang Wong
A slow J/psi excess exists in the inclusive B -> J/psi+X spectrum, and is indicative of some hadronic effect. From color octet nature of c cbar pair in b-> c cbar s decay, one such…
