Measurement of Branching Fraction and CP Violation Parameters in B0 → a1±(1260) π∓ Decays — •Jeremy Dalseno — Max-Planck-Institut für Physik, München, Deutschland
We present a measurement of the branching fraction and time-dependent CP violation parameters in B0 → a1±(1260) π∓ decays. These decays are sensitive to the CKM phase φ2, of the unitarity triangle for Bd decays. The results are obtained from the final data sample containing 772 × 106 B B pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider.
