论文摘要
$ b_c $梅森对，包括伪苏卡氏态和矢量状态，高能量光子 - 光子相互作用的生产是在非质量量子量子染色体动力学（NRQCD）分解形式上的近代领先顺序（NLO）精度。评估了未来的$ e^+e^ - $ SQRT {s} = 250 $ GEV和$ 500 $ GEV的相应横截面。数值结果表明，NLO校正的包含应极大地抑制规模依赖性并提高预测可靠性。除了现象学的含义外，该过程的NLO QCD计算符合某些技术问题，这些问题已详细阐明，可能适用于其他相关研究。
The $B_c$ meson pair, including pairs of both pseudoscalar states and vector states, productions in high energy photon-photon interaction are investigated at the next-to-leading order (NLO) accuracy in the nonrelativistic quantum chromodynamics (NRQCD) factorization formalism. The corresponding cross sections at the future $e^+e^-$ colliders with $\sqrt{s}=250$ GeV and $500$ GeV are evaluated. Numerical result indicates that the inclusion of the NLO corrections shall greatly suppress the scale dependence and enhance the prediction reliability. In addition to the phenomenological meaning, the NLO QCD calculation of this process subjects to certain technical issues, which are elucidated in details and might be applicable to other relevant investigations.
