Measurements of hadronic B decays to excited-charm mesons, observation of a new charm resonance and construction of a silicon vertex detector for CLEO II.V

We describe measurements of the branching ratios BB -→D⋆+p- p-total =29.2+/-4.5+/-3.8+/-3.1 x10-4 BB-→ D⋆+p-p -non- res= 9.7+/-3.6+/-1.5+/-1.9x 10-4 BB-→ D12420 0p- BD1 24200→ D⋆+p- = 6.9+1.8-1.4 +/-1.1+/-0.4x 10-4 BB-→ D01 j= 12 p- BD01 &parl0;j= 12&parr0; →D⋆ +p- = 10.6+/-1.9+/-1.7+/-2.3x 10-4 BB-→ D⋆2 24600p- BD ⋆2 24600→ D⋆+p- = 3.1+/- 0.84+/-0.46+/-0.28x10 -4, using data collected by the CLEO II detector. These measurements provide the first observation of the D01j= 12 with a mass and width of 2.461+0.053-0.049GeV and 290+110 - 91MeV respectively. The mixing angles between the partial waves and strong phase shifts among the resonances are also measured assuming one possible parameterization of the amplitude. A method allowing full reconstruction of the signal without reconstruction of the D meson in the final state is used. The measurements are extracted using an four-dimensional, unbinned, maximum-likelihood fit to the distributions of the D⋆+p- mass and the decay angles.;The primary element of the CLEO II.V upgrade was the installation of a three-layer Silicon Vertexing Detector. The design and construction of this detector are described in detail.
