| Observation and Properties of the Orbitally Excited B*s2 Meson (2008) | |||||||||
Abstract | |||||||||
| We report the direct observation of the excited L = 1 state B*s2 in fully reconstructed decays to B+K-. The mass of the B*s2 meson is measured to be 5839.6 ± 1.1(stat) ± 0.7(syst) MeV/c2, and its production rate relative to the B+ meson is measured to be [1.15 ± 0.23(stat) ± 0.13(syst)]%. | |||||||||
