Non-dipolar Wilson links for transverse-momentum-dependent wave functions
Hsiang-nan Li, Yu-Ming Wang
We propose a new definition of a transverse-momentum-dependent (TMD) wave function with simpler soft subtraction for factorization of hard exclusive processes. The un-subtrac…
Glauber gluons in spectator amplitudes for decays
Hsiang-nan Li, Satoshi Mishima
We extract the Glauber divergences from the spectator amplitudes for two-body hadronic decays in the factorization theorem, where denotes the meson emit…
Quantum Chromodynamics (CERN-2014-001)
Hsiang-nan Li
I review the basics of perturbative QCD, including infrared divergences and safety, collinear and factorization theorems, and various evolution equations and resummation tech…
Jet substructures of boosted polarized top quarks
Yoshio Kitadono, Hsiang-nan Li
We study jet substructures of a boosted polarized top quark, which undergoes the semileptonic decay , in the perturbative QCD framework. The jet mass distribution (ene…
Direct CP asymmetries of three-body decays in perturbative QCD
Wen-Fei Wang, Hao-Chung Hu, Hsiang-nan Li +1
We propose a theoretical framework for analyzing three-body hadronic meson decays based on the perturbative QCD approach. The crucial nonperturbative input is a two-hadron dist…
Perturbative QCD study of decays to a pseudoscalar meson and a tensor meson
Qin Qin, Zhi-Tian Zou, Xin Yu +2
We study two-body hadronic decays, with being a light pseudoscalar (tensor) meson, in the perturbative QCD approach. The CP-averaged branching ratios and the di…
