Study of Branching Fractions and CP-Violating Asymmetries in B Meson Decays to Rho And Pion Final State with the BABAR Detector

We present results for measurements of the decays to charmless final states of B0 meson to ηK0, ηω, [Formula: see text] with [Formula: see text], and of B+ to ηρ+, η′π+. Analyses are based on data taken with the BABAR detector at the PEP-II asymmetric e+e- collider at SLAC. We measure the following branching fractions in units of [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text]. The charge asymmetries are [Formula: see text] and [Formula: see text]. First error is statistical, the second systematic. All results are preliminary.

Final State Interactions

Analysis of charged and neutral B meson decays into π+π-K, K+K-K and [Formula: see text] is performed using a unitary representation of the ππ and [Formula: see text] final state interactions. Comparison of the theoretical model with the experimental data of the Belle and BaBar Collaborations indicates that charming penguin contributions are necessary to describe the B → f0(980) K and B → ρ(770)0 K decays.

Babar Detector

Recent BaBar results on rare B decays involving flavor changing neutral currents are presented. New measurements of the CP asymmetries in b→sγ and B→K*γ decays are reported as well as B→K(*)l+l- and b→sl+l- branching ratio measurements. The data sample comprises [Formula: see text] decays collected with the BaBar detector at the PEP-II e+e- storage ring.
