Pion transition form factor in k_T factorization
Hsiang-nan Li, Satoshi Mishima
It has been pointed out that the recent BaBar data on the pi gamma^* -> gamma transition form factor F_{pi gamma}(Q^2) at low (high) momentum transfer squared Q^2 indicate an asymp…
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…
Fourth Generation CP Violation Effect on B -> K pi, phi K and rho K in NLO PQCD
Wei-Shu Hou, Hsiang-nan Li, Satoshi Mishima +1
We study the effect from a sequential fourth generation quark on penguin-dominated two-body nonleptonic B meson decays in the next-to-leading order perturbative QCD formalism. With…
Gluonic contribution to form factors
Yeo-Yie Charng, T. Kurimoto, Hsiang-nan Li
We calculate the flavor-singlet contribution to the transition form factors from the gluonic content of the meson in the large-recoil region using…
Penguin-dominated B -> PV decays in NLO perturbative QCD
Hsiang-nan Li, Satoshi Mishima
We study the penguin-dominated B -> PV decays, with P (V) representing a pseudo-scalar (vector) meson, in the next-to-leading-order (NLO) perturbative QCD (PQCD) formalism, concent…
Puzzles in physics
Hsiang-nan Li
I discuss some puzzles observed in exclusive meson decays, concentrating on the large difference between the direct CP asymmetries in the and $B^\pm\to π^0…
