Hot topics on B physics from the BaBar experiment

摘要

We present here the measurements of branching fractions and CP-asymmetry parameters for the hadronic decays B~0 →p~0p~0, B~0 →a_1(1260)~-K~+,B~0→ K_s~0π~0,B→D~0(D~0)K~(*0), B→D~((*))K~((*)), B~+ → π~+,andB~0→K~+π~-π~0. The results are obtained from a data sample ofup to 427 million BB pairs produced by e~+e~-annihilation at the T(4S) resonancecollected with the BaBar detector at the PEP2 asymmetric-energy B-factory atSLAC.
