and threshold resummations
Hsiang-nan Li
We demonstrate that both the and threshold resummations can be performed in the Collins-Soper resummation formalism by evaluating soft gluon emissions with infrared cutoffs f…
Perturbative QCD analysis of exclusive meson decays
Hsiang-nan Li
We review the perturbative QCD formalism for exclusive heavy meson decays, concentrating on the three-scale factorization theorem for nonleptonic processes. The formalism is then e…
A New Unified Evolution Equation
Jyh-Liong Lim
WE propose a new unified evolution equation for parton distribution functions appropriate for both large and small Bjorken x. Compared with the Ciafaloni- Catani-Fiorani-Marchesini…
Unified derivation of 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…
