Description:
Author(s): Huey-Wen Lin, Jiunn-Wei Chen, Xiangdong Ji, Luchang Jin, Ruizi Li, Yu-Sheng Liu, Yi-Bo Yang, Jian-Hui Zhang, and Yong Zhao ( LP 3 Collaboration) We present a state-of-the-art calculation of the isovector quark-helicity Bjorken- x distribution in the proton using lattice-QCD ensembles at the physical pion mass. We compute quasidistributions at proton momenta P z ∈ { 2.2 , 2.6 , 3.0 } GeV on the lattice and match them systematically to the physical par... [Phys. Rev.
