Abstract A study of χ b meson production at LHCb is performed on proton–proton collision data, corresponding to 3.0 fb − 1 of integrated luminosity collected at centre-of-mass energies √ s = 7 and 8 TeV. The fraction of ϒ( nS ) mesons originating from χ b decays is measured as a function of the ϒ transverse momentum in the rapidity range 2 . 0 < y ϒ < 4 . 5. The radiative transition of the χ b ( 3P ) meson to ϒ( 3S ) is observed for the first time. The χ b1 ( 3P ) mass is determined to be where the first uncertainty is statistical and the second is systematic.
