Query: $J/\psi$ production associated with a $W$-boson at the $7 TeV$ LHC   We calculate the complete next-to-leading order (NLO) QCD corrections to the
$J/\psi +W$ associated production within the factorization formalism of
nonrelativistic QCD at the $7 TeV$ LHC. We provide the numerical results for
the leading-order (LO), NLO QCD corrected differential cross sections of the
$J/\psi$ transverse momentum by adopting the event selection criteria requested
by the ATLAS experiment. We find that the differential cross section at the LO
is significantly enhanced by the NLO QCD corrections.
