Doubly Charmful Baryonic B Decays
Hai-Yang Cheng, Chun-Khiang Chua, Shang-Yuu Tsai
There are two apparent puzzles connected with the two-body and three-body doubly charmed baryonic B decays. First, earlier calculations based on QCD sum rules or the diquark model…
Extracting the unitarity angle gamma in Bs to D0 h0, D0bar h0 Decays
Chun-Khiang Chua
The recently observed color-suppressed B0bar to D0 pi0, D0 eta, D0 eta', Ds+ K-, D0 K0bar, D0 rho0 and D0 omega decay modes all have rates larger than expected. The color-suppresse…
Charmless hadronic B decays involving scalar mesons: Implications to the nature of light scalar mesons
Hai-Yang Cheng, Chun-Khiang Chua, Kwei-Chou Yang
The hadronic charmless B decays into a scalar meson and a pseudoscalar meson are studied within the framework of QCD factorization. Although the light scalar mesons and…
CP-violating asymmetries in B^0 decays to K^+K^-K_{S(L)}^0 and K_S^0K_S^0K_{S(L)}^0
Hai-Yang Cheng, Chun-Khiang Chua, Amarjit Soni
Decay rates and time-dependent and direct CP asymmetries in the decays and are studied. Resonant and nonresonant contributions to the thr…
Implications of Bbar to D0 h0 Decays on Bbar to D Kbar, Dbar Kbar Decays
Chun-Khiang Chua, Wei-Shu Hou
The recently observed color suppressed B0bar to D0 pi0, D0 eta, D0 eta', Ds+ K-and D0 K0bar decay modes all have rates larger than expected, hinting at the presence of final state…
Effects of Final-state Interactions on Mixing-induced CP Violation in Penguin-dominated B Decays
Hai-Yang Cheng, Chun-Khiang Chua, Amarjit Soni
Motivated by the recent indications of the possibility of sizable deviations of the mixing-induced CP violation parameter, , in the penguin-dominated transitio…
