Abstract

We analyze the exclusive charmonium J/ψ+η_c pair production in e⁺e^- annihilation using the nonfactorized perturbative QCD and the light-front quark model(LFQM) that goes beyond the peaking approximation. We effectively include all orders of higher twist terms in the leading order of QCD coupling constant and compare our nonfactorized analysis with the usual factorized analysis in the calculation of the cross section. Our nonfactorized result enhances the NRQCD result by a factor of 3 ∼ 4 at √s = 10.6 GeV.
