NLO QCD对$Z^0$衰变中$B_c$介子产生的修正

The NLO QCD Corrections to $B_c$ Meson Production in $Z^0$ Decays

Cong-Feng Qiao, Li-Ping Sun, Rui-Lin Zhu

摘要:

在强相互作用下,用次领先阶(NLO)精度计算了$Z^0$到$B_c$介子的衰变宽度.数值计算表明,非线性振荡对该过程的修正是显著的。结果的量子色动力学(QCD)重整化标度依赖性明显降低,从而减少了首阶计算中的不确定性。

英文摘要:

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.
