Polarized decay in perturbative QCD

Hsien-Hung Shih, Shih-Chang Lee, Hsiang-nan Li

We study the polarized baryon semileptonic decay using perturbative QCD factorization theorem. In this approach heavy baryon transition form factors are…

A Review of pQCD Calculations of Electromagnetic Form Factors of Hadrons

Pankaj Jain, Bijoy Kundu, Hsiang-nan Li +2

We review the current status of perturbative QCD calculation of hadronic electromagnetic form factors.

Effects of threshold resummation

Hung-Liang Lai, Hsiang-nan Li

We investigate effects of threshold resummation of logarithmic corrections in Mellin space quantitatively. Threshold resummation leads to enhancement of next-to-leading-ord…

Applicability of perturbative QCD to decays

Hsien-Hung Shih, Shih-Chang Lee, Hsiang-nan Li

We develop perturbative QCD factorization theorem for the semileptonic heavy baryon decay , whose form factors are expressed as the convolutions of hard qua…

Perturbative QCD analysis of b-hadron lifetimes

Hsiang-nan Li

We develop perturbative QCD factorization theorems for inclusive b-hadron decays, in which radiative corrections characterized by the hadronic scale, the b-hadron mass, and the W b…

PQCD analysis of exclusive B meson decays

Hsiang-nan Li

The perturbative QCD formalism for exclusive heavy meson decays, especially the three-scale factorization theorem for nonleptonic modes is reviewed and compared to the conventional…
