微扰量子场论研讨会

In this talk, I will report the matching of parton distribution functions (PDFs) in Large Momentum Effective Theory (LaMET). First I will report the matching of gluon and quark PDFs in regularization independent momentum subtractioin (RI/MOM) scheme. Then I will report the next-to-next-to-leading order (NNLO) corrections to the nonsinglet quark quasi distribution functions.

The contribution of high dimensional operators in effective field theory becomes important as the experimental precision increases in LHC and future colliders. However, it can be very difficult to generate and classify these operators since the number of operators increases very fast as dimension increases. We propose a systematical method to generate and classify pure gluon operators with a...
