英文摘要: We study the gamma exclusive decay into double charmonium, specifically, the S-wave charmonium J/psi plus the P-wave charmonium chi(c0,1,2) in the nonrelativistic QCD factorization framework. Three distinct decay mechanisms, i. e., the strong, electromagnetic, and radiative decay channels, are included, and their interference effects are investigated. The decay processes gamma (1S; 2S; 3S) J/psi + chi(c0,1,2) are predicted to have the branching fractions of order 10(-6), which should be observed in the prospective Super B factory.
