Global analysis of B-->PP, PV charmless decays with QCD factorization
Dongsheng Du
The global analysis of B-->PP, PV charmless decays with QCD factorization (QCDF) is presented. The predictions of QCDF are in good agreement with experiments. The best fitted CKM a…
The one loop renormalization of the effective Higgs sector and its implications
Qi-Shu Yan, Dong-Sheng Du
We study the one-loop renormalization the standard model with anomalous Higgs couplings () by using the background field method, and provide the whole divergence structure…
The renormalization of the effective gauge Lagrangian with spontaneous symmetry breaking: the U(1) case
Qi-Shu Yan, Dong-Sheng Du
We study the renormalization of the nonlinear effective U(1) Lagrangian up to with spontaneous symmetry breaking. The problems of the quartic divergences and of the trunca…
The renormalization of the effective gauge theory with spontaneous symmetry breaking: the case
Q. S. Yan, D. S. Du
We formulate the electroweak chiral Lagrangian in its mass eigenstates, and study the its one-loop renormalization and provide its renormalization group equations to the same order…
QCD Factorization For B Decays To Two Light Pseudoscalars Including Chirally Enhanced Corrections
Dongsheng Du, Deshan Yang, Guohuai Zhu
Since b quark mass is not asymptotically large, chirally enhanced corrections which arise from twist-3 wave functions may be important in B decays. We thus evaluate the hadronic ma…
