Observation of muonic Dalitz decays of chib mesons and precise spectroscopy of hidden-beauty states

Aaij, R. ; Ruiz-Vidal, Joan LU and Zunica, G. (2024) In Journal of High Energy Physics 2024(10).
Abstract
The decays of the χb1(1P), χb2(1P), χb1(2P) and χb2(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. © The Author(s) 2024.
