Abstract
We report a measurement of resonance parameters of the orbitally excited (L=1) narrow B0 mesons in decays to B(*)+Ï€- using 1.7fb-1 of data collected by the CDF II detector at the Fermilab Tevatron. The mass and width of the B2*0 state are measured to be m(B2*0)=5740.2-1.8+1. 7(stat)-0.8+0.9(syst)MeV/c2 and Î"(B2*0)=22.7-3.2+3.8(stat)-10. 2+3.2(syst)MeV/c2. The mass difference between the B2*0 and B10 states is measured to be 14.9-2.5+2.2(stat)-1.4+1.2(syst)MeV/c2, resulting in a B10 mass of 5725.3-2.2+1.6(stat)-1.5+1.4(syst)MeV/c2. This is currently the most precise measurement of the masses of these states and the first measurement of the B2*0 width. © 2009 The American Physical Society.
