Resolving B-CP Puzzles in QCD Factorization
Hai-Yang Cheng, Chun-Khiang Chua
Within the framework of QCD factorization (QCDF), power corrections due to penguin annihilation can account for the observed rates of penguin-dominated two-body decays of meson…
Study of \bar B\to Λ_c\bar Λ_c and \bar B\to Λ_c\bar Λ_c \bar K
Hai-Yang Cheng, Chun-Khiang Chua, Yu-Kuo Hsiao
We study the doubly charmful two-body and three-body baryonic B decays and . As pointed out before, a naive estimate o…
Scalar and Pseudoscalar Glueballs
Hai-Yang Cheng
We employ two simple and robust results to constrain the mixing matrix of the isosinglet scalar mesons , , : one is the approximate SU(3) symmetry…
Understanding B -->J/Ψϕin the Standard Model
Ying Li, Hai-Yang Cheng
The rare decay can proceed in four distinct mechanisms: (i) production of the via tri-gluon fusion, (ii) photoproduction of the or , (iii) final-s…
Pseudoscalar glueball mass from -- mixing
Hai-Yang Cheng, Hsiang-nan Li, Keh-Fei Liu
We deduce the mass of the pseudoscalar glueball from an -- mixing formalism based on the anomalous Ward identity for transition matrix elements. With the inputs from…
Theoretical Overview of Hadronic Three-body B Decays
Hai-Yang Cheng
Charmless 3-body decays of B mesons are studied in a simple model based on the factorization approach. We have identified two distinct sources of nonresonant contributions: a small…
