Next-to-next-to-leading-order QCD corrections to J/ψ plus η c production at the B factories
Abstract In this paper, we calculate the next-to-next-to-leading-order (NNLO) QCD corrections to e + e − → J/ψ + η c at the B factories. After including the NNLO corrections, the cross section of e + e − → J/ψ +η c is enhanced by about 17%, and the perturbative series of the prediction shows the con...
