Description
In this talk, I will discuss the impact of one-loop QCD corrections[1] to the differential distributions of $J/\psi$ and $\Upsilon$ mesons produced in inclusive $\gamma \gamma$ collisions for the kinematical conditions of LEP and future high-energy $e^+e^-$ facilities. Firstly, I will focus on the pure QED processes $\gamma + \gamma \to Q\bar{Q}(^3S^{[1]}_1) +\gamma$, which only receive virtual corrections. Then I will discuss QCD corrections to the single-resolved contribution, whose high-energy behavior is known to be perturbatively unstable[2]. I will finally discuss the former process as a contribution to the exclusive production of $J/\psi+\gamma$ in ultra-peripheral heavy-ion collisions at the LHC.
