Abstract
We present a complete study on the
pair hadroproduction at next-to-leading order (NLO) in the nonrelativstic-QCD (NRQCD) framework with the pair of
in either
or
fock state. We found that the contribution of the
channel at NLO is essential, and for ATLAS, the NRQCD results can describe the experimental data to a certain extent.
