PandaXII constraints on spindependent WIMPnucleon effective interactions
/ Xia, Jingkai ; Abdukerim, Abdusalam ; Chen, Wei ; Chen, Xun ; et al
We present PandaXII constraints on candidate WIMPnucleon effective interactions involving the nucleon or WIMP spin, including, in addition to standard axial spindependent (SD) scattering, various couplings among vector and axial currents, magnetic and electric dipole moments, and tensor interactions.

Factorization theorem relating Euclidean and lightcone parton distributions
/ Izubuchi, Taku ; Ji, Xiangdong ; Jin, Luchang ; Stewart, Iain W. ; et al
In a largemomentum nucleon state, the matrix element of a gaugeinvariant Euclidean Wilson line operator accessible from lattice QCD can be related to the standard lightcone parton distribution function through the largemomentum effective theory (LaMET) expansion. [...]

Renormalization in Large Momentum Effective Theory of Parton Physics
/ Ji, Xiangdong ; Zhang, JianHui ; Zhao, Yong
In the largemomentum effective field theory approach to parton physics, the matrix elements of nonlocal operators of quark and gluon fields, linked by straight Wilson lines in a spatial direction, are calculated in lattice quantum chromodynamics as a function of hadron momentum. [...]
