Abstract

The decays of the χ_b1(1P), χ_b2(1P), χ_b1(2P) and χ_b2(2P) mesons into the Υ(1S)μ⁺μ⁻ final state are observed with a high significance using proton-proton collision data collected with the LHCb detector and corresponding to an integrated luminosity of 9 fb⁻¹. The newly observed decays together with the Υ(2S) → Υ(1S)π⁺π⁻ and Υ(3S) → Υ(2S)π⁺π⁻ decay modes are used for precision measurements of the mass and mass splittings for the hidden-beauty states.
