Charmonium pair production in ultraperipheral collision

Abstract We study the exclusive double charmonium $$(J/\psi {-} J/\psi $$ ( J / ψ - J / ψ and $$\eta _c {-} \eta _c)$$ η c - η c ) production through photon–photon fusion via ultraperipheral collision (UPC) at the HL-LHC and FCC with next-to-leading order (NLO) QCD predictions in the framework of no...
