Query: $\Upsilon(1S)$ prompt production at the Tevatron and LHC in
  nonrelativistic QCD   With nonrelativistic QCD factorization, we calculate the $\Upsilon(1S)$
prompt production at hadron colliders at next-to-leading order in $\alpha_s$.
In addition to the color-singlet contribution, color-octet channels (especially
the P-wave channel) up to $O(v^4)$ are all considered. Aside from direct
production, the feed-down contributions from higher excited S-wave and P-wave
$b\bar b$ states to $\Upsilon(1S)$ production are also included. We use the
potential model estimates as input for color-singlet long-distance matrix
elements (LDMEs). While for color-octet contributions, we find they can be
approximately described by three LDMEs: $\mo{}{3}{S}{1}{8}$,
$\mo{}{1}{S}{0}{8}$ and $\mo{}{3}{P}{0}{8}$. By fitting the Tevatron data we
can determine some linear combinations of these LDMEs, and then use them to
predict $\Upsilon(1S)$ production at the LHC. Our predictions are consistent
with the new experimental data of CMS and LHCb.
