$\Upsilon(1S)$ prompt production at the Tevatron and LHC in nonrelativistic QCD

Wang, Kai, Ma, Yan-Qing, Chao, Kuang-Ta

Understand

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).
