Complete Nonrelativistic-QCD Prediction for Prompt Double $J/\psi$ Hadroproduction

Abstract

We perform a complete study of prompt double $J/\psi$ hadroproduction at leading order in the nonrelativistic-QCD factorization framework by including all possible pairings of the $c\bar{c}$ Fock states ${}^1{S}_0^{[8]}$, ${}^3{S}_1^{[1,8]}$, and ${}^3{P}_J^{[1,8]}$ with $J=0,1,2$. We find that the ${}^1{S}_0^{[8]}$ and ${}^3{P}_J^{[8]}$ channels of $J/\psi$ and ${\psi }^{\prime }$ production and the ${}^3{P}_J^{[1]}$ and ${}^3{S}_1^{[8]}$ channels of ${\chi }_{cJ}$ production, which have been overlooked so far, greatly dominate at large invariant masses and rapidity separations of the $J/\psi$ pair, and that their inclusion nearly fills the large gap between previous incomplete predictions within the color-singlet model and the recent measurement by the CMS Collaboration at the CERN LHC, leaving room for next-to-leading-order corrections of typical size.
