Next-to-leading order QCD and relativistic corrections to $Z \to J / ψ + Υ (n S)$

Guang-Yu Wang, Xu-Chang Zheng, Guang-Zhi Xu

In this paper, we calculate the decay widths and branching fractions for the decays $Z \to J / ψ + Υ (n S)$ ( $n = 1, 2, 3$ ) at future super $Z$ factory and at the CEPC/FCC-ee, including both…

Improved analysis of double $J / ψ$ production in $Z$ -boson decay

Guang-Yu Wang, Xing-Gang Wu, Xu-Chang Zheng +2

In this paper, we present an improved calculation for the decay rate of the rare $Z$ -boson decay into $J / ψ + J / ψ$ . This decay is dominated by the photon fragmentation mechanism, i.e…

$Z$ -boson decays into $S$ -wave quarkonium plus a photon up to $O (α_{s} v^{2})$ corrections

Guang-Yu Wang, Xu-Chang Zheng, Xing-Gang Wu +1

In this paper, we calculate the decay widths and branching fractions for the decays $Z \to H + γ$ up to $O (α_{s} v^{2})$ accuracy within the framework of nonrelativistic QCD, w…

Higgs boson decays to $B_{c}$ meson in the fragmentation-function approach

Xu-Chang Zheng, Xing-Gang Wu, Xi-Jie Zhan +2

In the paper, we present a calculation of the decay widths for the Higgs boson decays to the $B_{c}$ , $B_{c}^{*}$ , $B_{c} (2^{1} S_{0})$ and $B_{c}^{*} (2^{3} S_{1})$ mesons using the fragmentation-functi…

Inclusive production of heavy quarkonium $η_{Q}$ via $Z$ boson decays within the framework of nonrelativistic QCD

Xu-Chang Zheng, Chao-Hsi Chang, Xing-Gang Wu +2

In the paper, the inclusive production of heavy quarkonium $η_{Q}$ ( $Q = b$ or $c$ ) via $Z$ boson decays within the framework of nonrelativistic QCD effective theory are studied. The c…
