Analysis of B-> ϕK Decays in QCD Factorization
Hai-Yang Cheng, Kwei-Chou Yang
We analyze the decay within the framework of QCD-improved factorization. We found that although the twist-3 kaon distribution amplitude dominates the spectator interactio…
The CP violating phase from global fit of rare charmless hadronic B decays
X. -G. He, Y. -K. Hsiao, J. -Q. Shi +2
We study constraints on the CP violating phase in the Kobayashi-Maskawa model using available experimental data. We first follow the conventional method to up date the constrai…
Decays in QCD Factorization
Hai-Yang Cheng, Kwei-Chou Yang
The hadronic decays are interesting because experimentally they are the only color-suppressed modes which have been measured, and theoretically they are calculable…
Implications of Recent Measurements of Nonleptonic Charmless B Decays
Hai-Yang Cheng
Implications of recent measurements of hadronic charmless B decays are discussed.
The nucleon spin structure in a simple quark model
Bo-Qiang Ma, Ivan Schmidt, Jian-Jun Yang
We investigate the spin structure of the nucleon in an extended Jaffe-Lipkin quark model. In addition to the conventional structure, different admixtures in t…
Out-of-equilibrium Photon Production from Disoriented Chiral Condensates
Da-Shin Lee, Kin-Wang Ng
We study the production of photons through the non-equilibrium relaxation of a disoriented chiral condensate. We propose that to search for non-equilibrium photons in the direct ph…
