D.; Alkhazov, G.; Alton, A.Made available in DSpace on 2022-04-28T20:32:29Z (GMT). No. of bitstreams: 0 Previous issue date: 2007-10-23; This Letter presents the first strong evidence for the resolution of the excited B mesons B1 and B2* as two separate states in fully reconstructed decays to B+(*)Ï€-. The mass of B1 is measured to be 5720.6Â.±2.4Â.±1.4Â.€‰Â.€ ‰MeV/c2 and the mass difference ÎM between B2* and B1 is 26.2Â.±3.1Â.±0. 9Â.€‰...
