Description:
Author(s): Kai Wang, Yan-Qing Ma, and Kuang-Ta Chao We analytically calculate the cross sections of double charmonium production in e + e - → J / ψ ( ψ (2 S )) χ c J ( J =0 , 1, 2) at next-to-leading order (NLO) in α s in nonrelativistic QCD, and confirm factorization of these processes. In contrast to χ c 0 production, for which the NLO correction is large and positive,... [Phys. Rev. D 84, 034022] Published Thu Aug 11, 2011
