Perturbative pion form factor reexamined
David Tung, Hsiang-nan Li
We recalculate the pion electromagnetic form factor based on the perturbative QCD formalism that includes the Sudakov resummation. We take into account the evolution of the pion wa…
Some aspects of the BFKL evolution
Hsiang-nan Li
I review the recent progress in small physics, concentrating on the topics relevant to the BFKL evolution.
Solution of sign problem in heavy meson decays: nonfactorizable soft gluons in nonleptonic heavy meson decays
B. Tseng, Hsiang-nan Li
For the first time, a solution to the sign problem in heavy meson decay based on PQCD factorization theorems. The point is to include QCD evolution effort characteristic…
The resummation approach to evolution equations
Hsiang-nan Li
We derive the evolution equations of parton distribution functions appropriate in different kinematic regions in a unified and simple way using the resummation technique. They incl…
