Next-to-leading-order QCD corrections to $S$ - and $P$ -wave heavy quarkonium decay to $l^{+} l^{-} γ$

Zhi-Guo He, Xu-Dong Huang

In this work, we comprehensively study the total and differential decay widths of the radiative Dalitz decays $H \to l^{+} l^{-} γ$ up to QCD next-to-leading order (NLO) accuracy within…

Probing Heavy-Quark Spin Symmetry in Double $J / ψ$ Hadroproduction

Zhi-Guo He, Xiao-Bo Jin, Bernd A. Kniehl

We perform the first complete $O (α_{s}^{5})$ analysis of the prompt hadroproduction of $J / ψ$ pairs with large transverse momenta $p_{T}^{ψ ψ}$ in the nonrelativistic-QCD factori…

Relativistic corrections to gluon fragmentation into the $^{3} P_{J}^{[1, 8]}$ states

Zhi-Guo He, Bernd A. Kniehl, Peng Zhang

We compute relativistic corrections to the gluon fragmentation functions to $^{3} P_{J}^{[1, 8]}$ Fock states of heavy quarkonium within non-relativistic QCD factorization framework. W…

Relativistic corrections to prompt double charmonium hadroproduction near threshold

Zhi-Guo He, Xiao-Bo Jin, Bernd A. Kniehl

We calculate the relativistic corrections to prompt $J / ψ$ pair and $J / ψ + ψ (2 S)$ hadroproduction through the color-singlet channel within the framework of nonrelativistic QCD (NRQCD)…
