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/c(2), and its production rate relative to the B(+) meson is measured to be [1.15±0.23(stat)±0.13(syst)]%.
