Abstract:

 

I will first review the large momentum effective theory (LaMET) method that allows extraction of hadron parton distribution functions with lattice QCD. I will explain the advantage of using a hybrid renormalization scheme to treat lattice data, which can be related to the parton distributions extracted phenomenological once the matching kernels are known. I will then present our calculation of the unpolarized, helicity, and transversity isovector parton distribution functions and skewless generalized parton distributions of all hadrons in this scheme.

 

Brief biography:

Jiunn-Wei Chen is a Distinguished Professor of Physics at Taiwan University (NTU). He received his Ph. D. from the University of Washington, Seattle. Then he became postdocs at Maryland and MIT before joining the faculty of NTU. Prof. Chen is a nuclear theorist. He is perhaps most well known for his work on nuclear effective theory and its great simplification of weak interaction processes in nuclear physics, which was used by the SNO collaboration in their Nobel prize-winning experiment to solve the solar neutrino problem. In addition, Prof. Chen also has highly cited work on the cosmological constant problem, lattice QCD, and quantum phases. He is currently the director of the Center for Theoretical Physics at NTU and the deputy director of the National Center for Theoretical Sciences.
