Production of χb-mesons at LHC

الأصل · EN

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 χ₁,₂b states. We found, that the ratios of bottomonium and charmonium spin states are fundamentally complementary at different pₜ scales. We give predictions for the ratio of the n=2 and n=1 radial excitations production cross sections.
