Abstract:

The search for B0 decays to charmless isoscalar meson pairs was carried out. The B0→φφ decay is define as a pure penguin annihilation process with an expected branching fraction of order 19 in the standard model. It was found that the branching functions or limits bear on the accuracy with CP-violating asymmetry measurements. The charged particles from e+e- interactions were detected and their momenta was measured using a combination of a vertex tracker.

Abstract:

The study of D*sJ(2317)+ and D sJ(2460)+ meson production in B decays was reported. The decays B+→D(*sJ+̄D(*)0 and B0→D (*)sJ+ D(*̄ was observed. The branching functions for these modes was obtained based on the sample of 122.1 × 106 B̄B pairs collected with the BABAR detector at the PEP-II B factory. An angular analysis of DsJ(2460) + → D+s γ decays was also performed.

Abstract:

A measurement of the direct CP violating asymmetry in the decay B 0→K+π- is discussed using a data sample of 227×106 υ(4S)→BB̄ decays. It is found that direct CP violation does not involve particle-antiparticle oscillations. The data sample is collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at SLAC. The probability of observing an asymmetry is 1.3×10-5, in the absence of direct CP violation, corresponding to 4.2 standard deviations.

Abstract:

The time-dependent CP-violating (CPV) asymmetries in B0 → KS0π0 decays based on 124×10 6 υ(4S) → BB̄ decays are measured. The asymmetries are collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. The magnitudes of the direct CPV asymmetry and of the CPV asymmetry in the interference between mixing and decay are obtained in a sample containing 122 ± 16 signal decays. It is found that the first error is statistical in nature while the second is systematic.
