Description
In this talk, I will give a brief overview of the Lattice Parton Collaboration’s recent lattice QCD studies of TMD observables within the Large Momentum Effective Theory (LaMET) framework. The presentation will cover first-principles determinations of the soft function, the Collins–Soper evolution kernel, as well as several key TMD parton distributions, including the unpolarized and helicity TMDPDFs, the Boer–Mulders function, and the worm-gear function. I will also discuss the phenomenological implications of these results and their connections to ongoing and future experimental programs.
