Implications on the first observation of charm CPV at LHCb / Li, Hsiang-Nan (Taiwan, Inst. Phys.) ; Lü, Cai-Dian (Beijing, Inst. High Energy Phys.) ; Yu, Fu-Sheng (Lanzhou U.)
Very recently, the LHCb Collaboration observed the $CP$ violation (CPV) in the charm sector for the first time, with $\Delta A_{CP}^{\rm dir}\equiv A_{CP}(D^0\to K^+K^-)-A_{CP}(D^0\to \pi^+\pi^-)=(-1.54\pm0.29)\times10^{-3}$. [...]

Quantum Chromodynamics / Li, Hsiang-nan (Taiwan, Inst. Phys.)
I review the basics of perturbative QCD, including infrared divergences and safety, collinear and $k_T$ factorization theorems, and various evolution equations and resummation techniques for single- and double-logarithmic corrections. I then elaborate its applications to studies of jet substructures and hadronic two-body heavy-quark decays..

Two-photon collisions at LEP / Hsiang Nan Li
We study the effect of initial-state radiation in the double-tagged process ee to ee + hadrons by introducing the parton distribution functions associated with an electron, a positron, and a photon, which satisfy a set of Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) equations. It is observed that the radiation effect is not essential in most of the kinematic range. [...]
