The NLO QCD corrections to $B_c$($B_c^{\ast }$) production around $Z$ pole at an $e^{+}{e}^{-}$ collider

Xu-Chang Zheng, Chao-Hsi Chang, Tai-Fu Feng +1

Production of the $B_c$ and $B_c^{\ast }$ mesons at $Z$-factory (an $e^{+}{e}^{-}$ collider running at energies around $Z$ pole) is calculated up-to the next-to-leading order (NLO) QCD correct…
