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 $B$ 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 $B ˉ \to Λ_{c}^{+} Λ ˉ_{c}^{-}$ and $B ˉ \to Λ_{c}^{+} Λ ˉ_{c}^{-} K ˉ$ . 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 $f_{0} (1710)$ , $f_{0} (1500)$ , $f_{0} (1370)$ : one is the approximate SU(3) symmetry…

Understanding B -->J/Ψϕin the Standard Model

Ying Li, Hai-Yang Cheng

The rare decay $B ˉ_{d}^{0} \to J / ψ ϕ$ can proceed in four distinct mechanisms: (i) production of the $ϕ$ via tri-gluon fusion, (ii) photoproduction of the $J / ψ$ or $ϕ$ , (iii) final-s…
