Observation of excited b mesons in p$$\bar{p}$$ collisions a square √s = 1.8 TeV
- Massachusetts Inst. of Technology (MIT), Cambridge, MA (United States)
Production of orbitally excited (L = 1) states of B mesons, B**, is studied using a sample of nearly ten thousand partially reconstructed B mesons collected with the CDF detector from p$$\bar{p}$$ collisions at √s = 1.8 TeV. Ambiguities in the reconstruction of the B flavor and momentum are resolved. The fraction of b quarks that hadronize into an L = 1 state is measured to be 0.28 ± 0.06(stat) ± 0.03(syst), and the collective mass of the B** states is measured to be m(B1) = 5.71 ± 0.02 GeV/c2 given the mass splittings between the four states.
