NLO QCD corrections to exclusive quarkonium-pair production in photon–photon collision
Abstract We calculate the next-to-leading order (NLO) quantum chromodynamics (QCD) corrections to the exclusive processes $$\gamma +\gamma \rightarrow {\mathcal {Q}}+{\mathcal {Q}}$$ γ+γ→Q+Q , with $${\mathcal {Q}}=J/\psi ,\ \eta _c,\ \Upsilon $$ Q=J/ψ,ηc,Υ , or $$\eta _b$$ ηb , in the framework of...
