Production of ${\chi }_b$-mesons at LHC

Abstract

In the present paper, we discuss the $P$-wave bottomonium production within the both color octet and color singlet models in NLO at LHC energies. We calculate the production and the transverse momentum distributions of the ${\chi }_{1,2b}$ states. We found, that the ratios of bottomonium and charmonium spin states are fundamentally complementary at different $p_T$ scales. We give predictions for the ratio of the $n=2$ and $n=1$ radial excitations production cross sections.
