Abstract:

A search for the decays of D0 → e+e -, D0→ μ+μ- and D 0 → e±μ∓ was investigated. The analysis was based on 122 fb-1 of data collected on or near the γ(4S) resonance by the BABAR detector at the SLAC PEP-II asymmetric e+e- collider. The BABAR detector provided charged-particle tracking through a combination of five-layer double-sided silicon microstrip detector (SVT) and a 40-layer central drift chamber (DCH). The upper limits on the branching fractions are 1.2 x 10-6, 1.3 x 10-6 and 8.1 x 10-7.

Abstract:

The branching fractions for charmless decays of B mesons into the three-body final states B0→K+K-K 0 and B+K0sK0s was measured. It was found that the branching fractions and CP asymmetries were extracted in unbinned extended maximum likelihood fits. It was found that the K+K-K0S final state was dominated by a CP-enev component. The contributions from the signal reconstruction efficiency and form the modeling of the efficiency variation over the space was included to measure systematic uncertainities in the branching fraction.

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.
