The NLO QCD Corrections to $B_c$ Meson Production in $Z^0$ Decays
arXiv:1104.5587 · doi:10.1007/JHEP08(2011)131
Abstract
The decay width of $Z^0$ to $B_c$ meson is evaluated at the next-to-leading order(NLO) accuracy in strong interaction. Numerical calculation shows that the NLO correction to this process is remarkable. The quantum chromodynamics(QCD)renormalization scale dependence of the results is obviously depressed, and hence the uncertainties lying in the leading order calculation are reduced.
