Query: Associated production of $\Upsilon(1S)W$ at LHC in next-to-leading order
  QCD   We investigate the complete next-to-leading order (NLO) QCD corrections to
$\Upsilon(1S) +W$ production at the LHC, and predict theoretically the
distribution of the $\Upsilon(1S)$ transverse momentum. We analyse the
contributions from different components up to the QCD NLO in the \ppUW process.
Our results show that the \ppUW process has a large production rate and could
be potentially detected at the LHC. We see that the differential cross section
for the $\Upsilon(1S)$ direct-production at the LO is significantly enhanced by
the QCD corrections, and the $b\bar{b} [ ^3S_1^{(8)} ]$ contribution component
dominates in the whole plotted $p_T^{\Upsilon(1S)}$ region. We have also
calculated the $\Upsilon(1S)$ meson indirect-productions via feed-down decays
of $\Upsilon(2S)$, $\Upsilon(3S)$, $\chi_{b1}(1P)$, $\chi_{b2}(1P)$,
$\chi_{b1}(2P)$, and $\chi_{b2}(2P)$ mesons. We find that the $\Upsilon(1S)$
indirect-productions can give important contributions to the distribution of
$p_T^{\Upsilon(1S)}$ for the \ppUW process at the NLO. We conclude that the
studying the $\Upsilon(1S)+W$ production at the LHC could provide an
interesting opportunity in testing the nonrelativistic QCD factorization
formalism.
