N2 - The decays of the ?b1(1P), ?b2(1P), ?b1(2P) and ?b2(2P) mesons into the ?(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 ?(2S) ? ?(1S)p+p- and ?(3S) ? ?(2S)p+p- decay modes are used for precision measurements of the mass and mass splittings for the hidden-beauty states.
