B meson decays and Kobayashi-Maskawa matrix

Abstract

We compute Γ(B +→p p π +) and Γ(B 0→p p π +π −) by a dynamical model where one of the final pions are produced by Δ resonance decay. We also analyze the end-point behaviour of the electron spectrum in the decay→evX, by a calculated B meson wave function and partonic widths as given by QCD. By using recent data from the ARGUS Collaboration we obtain | V bc |=(4.8±0.4)×10 −2 and | V bu / V bc |=0.10±0.02.
