B_c介子对强子产生的NLO QCD修正

NLO QCD corrections to the $B_c$-pair hadroproduction

Zi-Qiang Chen, Long-Bin Chen, Cong-Feng Qiao

AI总结:

在非相对论QCD框架下计算B_c介子对在LHC的NLO截面,发现修正显著且可能超过领头阶,预示高亮度LHC可观测。

摘要:

在非相对论量子色动力学因子化框架下,研究了质子-质子碰撞中B_c介子对(包括赝标量态和矢量态的对)的产生,计算精度达到次领头阶(NLO)。评估了大型强子对撞机(LHC)在√s=14 TeV能量下的相应截面。数值结果表明,NLO修正显著,甚至超过领头阶贡献。考虑到预测的截面可观,B_c介子对产生有望在高亮度LHC实验中观测到。

英文摘要:

The $B_c$ meson pair, including pairs of pseudoscalar states and vector states, productions in proton-proton collisions are investigated at the next-to-leading order (NLO) accuracy in the nonrelativistic quantum chromodynamics factorization formalism. The corresponding cross sections at the Large Hadron Collider (LHC) with $\sqrt{s}=14\; \text{TeV}$ are evaluated. Numerical results indicate that the NLO corrections are substantial, and even dominate over the leading order contributions. Considering the predicted cross sections are sizable, the $B_c$-pair production is expected to be observable at the High-Luminosity LHC experiment.
