Theoretical Developments of the LaMET Approach to Parton Physics
January 07, 2020
The large-moment effective theory (LaMET) is a systematic approach to extract light-cone parton physics from equal-time matrix elements that are calculable in lattice QCD. Recent years have seen rapid developments of the LaMET approach which have been applied to various lattice calculations and led to much promising progress in this field. In this work, we will discuss the formalism of LaMET and its extension to parton distributions for the transverse structures, which are essential steps in the road map to obtaining the three-dimensional tomography of the hadrons from lattice QCD.
