Observation of the χb1 (3P) and χb2 (3P) and Measurement of their Masses

Albert M. Sirunyan, +2353 more

- 29 Aug 2018

- Physical Review Letters

TL;DR: This is the first time that the J=1 and 2 states are well resolved and their masses individually measured, and they are determined with respect to the world-average value of the ϒ(3S) mass, which has an uncertainty of 0.5 MeV.
