Asymmetries in B 0 → π + π −

B 0 / B 0 Decays to π + π − π 0 and K ± π ∓ π 0 in Regions Dominated by the ρ ± Resonance

We present preliminary measurements of direct and indirect CP -violating asymmetries in the decays of neutral B mesons to π+π−π0 and K±π∓π0 final states dominated by the ρ± resonance, using a time-dependent maximum likelihood analysis. The data sample comprises 88 × 106 Υ (4S) → BB decays (80.8 fb) collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. For the CP v...

Measurement of ∆ md in B 0 → D − ( K + π − π − ) π +

We measure the B 0 − B 0 mixing frequency ∆m d using ∼ 6000 B 0 → D − (K + π − π −)π + candidates from 36 pb −1 of data taken in physics runs of the LHCb experiment in 2010. We use opposite and same side tagging algorithms which were optimized and calibrated in an independent analysis [1]. The tagging performance on the B 0 → D − (K + π − π −)π + candidates used in this analyses is found to be ...

0 Quark - Hadron Duality , Factorization and Strong Phases in B 0 d → π + π − Decay

We investigate the hadronic description of the B 0 d → π + π − decay, with the aim to test the validity of quark-hadron duality, the factorization limit and the magnitude of the strong phases. We discuss the derivation of the dispersion relations in the Lehmann-Symanzik-Zimmermann formalism, the Goldberger-Treiman method to include inelastic effects in the spectral function and the consistency ...
