One-loop matching for transversity generalized parton distribution

26 Sep 2015  ·  Xiong Xiaonu, Zhang Jian-Hui ·

Recent developments showed that light cone parton distributions can be studied by investigating the large momentum limit of the so-called quasiparton distributions, which are defined in terms of spacelike correlators, and therefore can be readily computed on the lattice. These two distributions can be connected to each other by a perturbative factorization formula or matching condition that allows one to convert the latter into the former... Here we present the one-loop matching condition for the transversity generalized quark distribution in the nonsinglet case read more
