Next-to-next-to-leading-order QCD corrections to e+e− → J/ψηc at B factories

Next-to-next-to-leading-order QCD corrections to e+e− → J/ψηc at B factories

Within the nonrelativistic QCD (NRQCD) factorization framework, we compute the long-awaited O(αs2) corrections for the exclusive double charmonium production process at B factories, i.e., e+e−→J/ψ+ηc at s=10.58 GeV. We confirm that NRQCD factorization does hold at next-to-next-to-leading-order (NNLO...
