摘要：
We present a complete study on the J/Psi pair hadroproduction at next-to-leading order (NLO) in the nonrelativstic-QCD (NRQCD) framework with the pair of c (c) over bar in either (3)S(1)([1] )or S-1(0)[8] fock state. We found that the contribution of the (1)S(0)([8] )channel at NLO is essential, and for ATLAS, the NRQCD results can describe the experimental data to a certain extent.
