Parton distributions in the shockwave formalism
Shohini Bhattacharya, Chuan-Qi He, Zhong-Bo Kang +2
In this work, we calculate a broad class of parton distributions - including parton distribution functions (PDFs), transverse-momentum-dependent distributions (TMDs), generalized p…
Matching collinear factorization with color-glass condensate for inclusive and exclusive deep inelastic scattering
Shohini Bhattacharya, Chuan-Qi He, Zhong-Bo Kang +2
Collinear factorization and color-glass condensate (CGC) effective field theory are generally treated as separate approaches for calculating scattering amplitudes, valid in differe…
Two-loop QCD-corrections to
Xiang Chen, Xin Guan, Chuan-Qi He +1
We present a next-to-next-to-leading-order calculation within the nonrelativistic QCD framework for the process of . We find…
Single-inclusive hadron production in electron-positron annihilation at next-to-next-to-next-to-leading order in QCD
Chuan-Qi He, Hongxi Xing, Tong-Zhi Yang +1
Single-inclusive hadron production in electron-positron annihilation (SIA) represents the cleanest process for investigating the dynamics of parton hadronization, as encapsulated i…
Analytical two-loop amplitudes of at factories
Xiang Chen, Xin Guan, Chuan-Qi He +3
In double charmonium production, a long-standing challenge is that the theoretical predictions are not consistent with the measurements at B factories. Within the NRQCD framework,…
