11 Dec 2012 | | Abstract: | 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 $bar{b} [ ^3S_1^{(8)} ]$ 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. | | Source: | arXiv, 1212.2417 | | Services: | Forum | Review | PDF | Favorites | |
