Production of χb mesons at the LHC

In the present paper we discuss the P-wave bottomonium production within both color octet and color singlet models in next-to-leading order at LHC energies. We calculate the cross section and the transverse momentum distributions for the chi(1,2b) states. We obtain that the ratios of bottomonium and charmonium spin state production 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.
