dc.description.abstractThe decays of the χb1(1P), χb2(1P), χb1(2P) and χb2(2P) mesons into the Υ(1S)µ +µ − fnal state are observed with a high signifcance 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.
