Received 2 November 2007; revised 22 January 2008; published 28 February 2008
We report the direct observation of the excited L=1 state Bs2* in fully reconstructed decays to B+K-. The mass of the Bs2* 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)]%.
