Abstract
A study of χ[subscript b] meson production at LHCb is performed on proton–proton collision data, corresponding to 3.0 fb[superscript −1] of integrated luminosity collected at centre-of-mass energies √s = 7 and 8 TeV . The fraction of Υ(nS) mesons originating from χ[subscript b] decays is measured as a function of the Υ transverse momentum in the rapidity range 2.0
