Quasi-parton distribution functions: a study in the diquark spectator model
Leonard Gamberg, Zhong-Bo Kang, Ivan Vitev +1
A set of quasi-parton distribution functions (quasi-PDFs) have been recently proposed by Ji. Defined as the matrix elements of equal-time spatial correlations, they can be computed…
Sivers Asymmetry with QCD Evolution
Miguel G. Echevarria, Ahmad Idilbi, Zhong-Bo Kang +1
We analyze the Sivers asymmetry in both Drell-Yan (DY) production and semi-inclusive deep inelastic scattering (SIDIS), while considering properly defined transverse momentum depen…
Heavy Quarkonium Production at Collider Energies: Partonic Cross Section and Polarization
Zhong-Bo Kang, Yan-Qing Ma, Jian-Wei Qiu +1
We calculate the short-distance, QCD collinear-factorized coefficient functions for all partonic channels that include the production of a heavy quark pair at sho…
Pre-Town Meeting on Spin Physics at an Electron-Ion Collider
Elke-Caroline Aschenauer, Ian Balitsky, Leslie Bland +29
A polarized collider (Electron--Ion Collider, or EIC), with polarized proton and light-ion beams and unpolarized heavy-ion beams with a variable center--of--mass energy $\s…
Nucleon tensor charge from Collins azimuthal asymmetry measurements
Zhong-Bo Kang, Alexei Prokudin, Peng Sun +1
We investigate the nucleon tensor charge from current experiments by a combined analysis of the Collins asymmetries in two hadron production in annihilations and semi-incl…
Next-to-leading order transverse momentum-weighted Sivers asymmetry in semi-inclusive deep inelastic scattering: the role of the three-gluon correlator
Ling-Yun Dai, Zhong-Bo Kang, Alexei Prokudin +1
We study the Sivers asymmetry in semi-inclusive hadron production in deep inelastic scattering. We concentrate on the contribution from the photon-gluon fusion channel at ${\cal O}…
