NLO QCD corrections to pseudoscalar quarkonium production with two heavy flavors in photon-photon collision

Hao Yang, Zi-Qiang Chen, Cong-Feng Qiao

We calculate the next-to-leading order (NLO) quantum chromodynamics (QCD) corrections to $\gamma +\gamma \to {\eta }_c+c+\bar{c}$, $\gamma +\gamma \to {\eta }_b+b+\bar{b}$ and $\gamma +\gamma \to B_c+b+\bar{c}$ processes in the…
