${\rm Y}(nS)$ and ${\chi }_b(nP)$ production at hadron colliders in nonrelativistic QCD

Abstract

${\rm Y}(nS)$ and ${\chi }_b(nP)$ (n=1,2,3) production at the LHC is studied at next-to-leading order in ${\alpha }_s$ in nonrelativistic QCD. Feeddown contributions from higher ${\chi }_b$ and ${\rm Y}$ states are all considered for lower ${\rm Y}$ cross sections and polarizations. The long distance matrix elements (LDMEs) are extracted from the yield data, and then used to make predictions for the ${\rm Y}(nS)$ polarizations, which are found to be consistent with the measured polarization data within errors. In particular, the ${\rm Y}(3S)$ polarization puzzle can be understood by a large feeddown contribution from ${\chi }_b(3P)$ states. Our results may provide a good description for both cross sections and polarizations of prompt ${\rm Y}(nS)$ and ${\chi }_b(nP)$ production at the LHC.

arXiv commentThe text and abstract are substantially changed due to the change in the fitting procedure: we now extract LDMEs of ${\rm Y}(nS)$ and ${\chi }_{b}nP$ by fitting the yield data of the LHC (including cross sections measured by ATLAS, CMS, and LHCb), and then make predictions for the polarizations of ${\rm Y}(nS)$
