Charmless B Decays Involving Vector Mesons in Belle

Using the data sample of 10.5 fb-1 collected by the Belle detector, we searched for two-body charmless decays involving vector mesons. The clear signal signature of B+ -> phi K+ is seen and its branching fraction is measured to be (1.39+.32-.30 +- 0.2) X 10-5. The evidence for B+ -> rho pi+, B0 -> rho- pi+ and B+ -> phi K*+ is reported and their branching fractions are determined. No significant signals are observed for B0 -> phi K0S, -> phi K*0, -> rho- K+, B+ -> rho K+, -> omega pi+ and -> omega K+ only the 90% C.L. upper limits are given.Comment: 4 pages, Proceedings of the 4th International Conference on B Physics & CP Violation, Ise-Shima, Japan, February 19 - 23, 200

Nuclear matter with off-shell propagation

Symmetric nuclear matter is studied within the conserving, self-consistent T-matrix approximation. This approach involves off-shell propagation of nucleons in the ladder diagrams. The binding energy receives contributions from the background part of the spectral function, away form the quasiparticle peak. The Fermi energy at the saturation point fulfills the Hugenholz-Van Hove relation. In comparison to the Brueckner-Hartree-Fock approach, the binding energy is reduced and the equation of state is harde
