X(3860) production in association with $$J/\psi $$ J / ψ via $$e^{+}e^{-}$$ e + e - annihilation at Belle
Abstract In this paper, we study the X(3860) production associated with $$J/\psi $$ J / ψ via $$e^{+}e^{-}$$ e + e - annihilation at the next-to-leading-order (NLO) accuracy in $$\alpha _s$$ α s , within the nonrelativistic QCD (NRQCD) framework. With the hypothesis of $$J^{PC}_{X(3860)}=0^{++}$$ J...
