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

In a large-momentum nucleon state, the matrix element of a gauge-invariant Euclidean Wilson line operator accessible from lattice QCD can be related to the standard light-cone parton distribution function through the large-momentum effective theory (LaMET) expansion. [...]
