EEXICC: An event generator for doubly heavy baryon production at $e^{+} e^{-}$ colliders

Hong-Tai Li, Xu-Chang Zheng, Xing-Gang Wu +2

We present EEXICC, a Monte Carlo event generator designed to simulate the production of doubly heavy baryons ( $Ξ_{cc}$ , $Ξ_{b c}$ , and $Ξ_{bb}$ ) via $e^{+} e^{-}$ annihilation. Based on…

Production of doubly heavy quarkonium associated with two heavy quarks via top quark decays

Juan-Juan Niu, Xu-Chang Zheng, Hong-Hao Ma

In this paper, we analyze the $1 \to 4$ decay channel for the production of doubly heavy quarkonium, $(b c ˉ)$ or $(c c ˉ)$ , via top-quark decays, $t \to (b\bar{c}) +…

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…

Renormalization and Factorization Scale-Invariant Predictions for the Higgs Rare Decay $H \to J / ψ + γ$ via the Principle of Maximum Conformality

Qi-Sha Ran, Xing-Gang Wu, Jiang Yan +2

We investigate the $J/ψ$ direct production mechanism in the rare exclusive Higgs decay $H\to J/ψ+γ$ within nonrelativistic QCD (NRQCD), which provides a clean probe for extract…

Fragmentation functions for gluon into $P$ -wave $B_{c}$ mesons

Xu-Chang Zheng, Xing-Gang Wu

We calculate the fragmentation functions for a gluon into $P$ -wave $B_{c}$ mesons within the nonrelativistic QCD factorization framework, incorporating color-singlet and color-octet…

Determination of $∣ V_{cb} ∣$ using Bayesian analysis of the $B \to D^{*} ℓ ν ˉ_{ℓ}$ semileptonic decay width with four-loop QCD corrections

Wang Li, Xing-Gang Wu, Hua Zhou +1

The Cabibbo-Kobayashi-Maskawa matrix element $∣ V_{cb} ∣$ is an important Standard Model parameter, whose value can be determined by using the semi-leptonic decay $B\rightarrow D…
