A More Precise Extraction of |V_{cb}| in HQEFT of QCD
W. Y. Wang, Y. L. Wu, Y. A. Yan +2
The more precise extraction for the CKM matrix element |V_{cb}| in the heavy quark effective field theory (HQEFT) of QCD is studied from both exclusive and inclusive semileptonic B…

1/m_Q order contributions to B \to πl νdecay in HQEFT
W. Y. Wang, Y. L. Wu, M. Zhong
Contributions to B\to πl νdecay from 1/m_Q order corrections are analyzed in the heavy quark effective field theory (HQEFT) of QCD. Transition wave functions of 1/m_Q order are cal…
