Two-loop QCD-corrections to $e^{+} e^{-} \to Z^{*} \to J / ψ + J / ψ$

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 $e^{+} e^{-} \to Z^{*} \to J / ψ + J / ψ$ . We find t…

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…

Analytical two-loop amplitudes of $e^{+} e^{-} ⟶ J / ψ + η_{c}$ at $B$ 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,…

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…
