K1(1270)-K1(1400) Mixing Angle and New-Physics Effects in B to K1 l+ l- Decays
Hisaki Hatanaka, Kwei-Chou Yang
We study semileptonic B meson decays B to K_1(1270) l^+ l^- and K_1(1400) l^+ l^- (l=e, mu, tau), where the strange P-wave mesons, K_1(1270) and K_1(1400), are the mixtures of the…
(Pseudo-) Scalar Operators in the MSSM and B to phi K^*, K eta(') Decays
Hisaki Hatanaka, Kwei-Chou Yang
We study the effect of b to s sbar s scalar/pseudoscalar operators, originating from penguin diagrams of neutral Higgs bosons in the MSSM, in B to K eta(') and B to phi K^* decays.…
Pseudoscalar and Scalar Operators of Higgs-Penguins in the MSSM and B to phi K^*, K eta(') Decays
Hisaki Hatanaka, Kwei-Chou Yang
We study the effect of b to s sbar s scalar/pseudoscalar operators in B to K eta('), phi K^* decays. In the minimal supersymmetric standard model (MSSM), such scalar/pseudoscalar o…
Hadronic charmless B decays B-> AP
Hai-Yang Cheng, Kwei-Chou Yang
The two-body hadronic decays of B mesons into pseudoscalar and axial vector mesons are studied within the framework of QCD factorization. The light-cone distribution amplitudes (LC…
Charmless B decays to a scalar meson and a vector meson
Hai-Yang Cheng, Chun-Khiang Chua, Kwei-Chou Yang
The hadronic charmless B decays into a scalar meson and a vector meson are studied within the framework of QCD factorization. The main results are: (i) The decay rates for the $f_0…
Branching Ratios and CP Asymmetries of B \to a_1(1260) πand a_1(1260) K Decays
Kwei-Chou Yang
We present the studies of the decays and within the framework of QCD factorization. Due to the G-parity, unlike the vector meson, the chiral-odd tw…
