One-Loop Matching for Parton Distributions: Non-Singlet Case
Xiaonu Xiong, Xiangdong Ji, Jian-Hui Zhang +1
We derive one-loop matching condition for non-singlet quark distributions in transverse-momentum cut-off scheme, including unpolarized, helicity and transversity distributions. The…
Gluon Helicity Delta G from a Universality Class of Operators on a Lattice
Yoshitaka Hatta, Xiangdong Ji, Yong Zhao
We show that the total gluon helicity in a polarized nucleon can be calculated on a Euclidean lattice through a universality class of QCD operators that describe the helicity…
A Naturally Light Sterile neutrino in an Asymmetric Dark Matter Model
Yongchao Zhang, Xiangdong Ji, Rabindra N. Mohapatra
A recently proposed asymmetric mirror dark matter model where the mirror sector is connected with the visible one by a right handed neutrino portal, is shown to lead naturally to a…
Parton Physics on Euclidean Lattice
Xiangdong Ji
I show that the parton physics related to correlations of quarks and gluons on the light-cone can be studied through the matrix elements of frame-dependent, equal-time correlators…
Physics of Gluon Helicity Contribution to Proton Spin
Xiangdong Ji, Jian-Hui Zhang, Yong Zhao
The total gluon helicity in a polarized proton, measurable in high-energy scattering, is shown to be the large momentum limit of a gauge-invariant but non-local, frame-dependent gl…
Reply to arXiv:1211.3957 and arXiv:1211.4731 by Leader et al. and arXiv:1212.0761 by Harindranath et al
Xiangdong Ji, Xiaonu Xiong, Feng Yuan
We reply to the recent comments on our published papers, Phys. Rev. Lett. 109 (2012) 152005 and Phys. Lett. B717 (2012) 214. We point out that the criticisms about the transverse p…
