This dissertation reports the measurement of the branching fractions of neutral and charged B meson decays to final states containing a K_1(1270) or K_1(1400) meson and a charged pion. The data, collected with the BaBar detector at the SLAC National Accelerator Laboratory, correspond to 454 million B Bbar pairs produced in e+ e- annihilation. We use the results to estimate the weak phase alpha from the time dependent CP asymmetries in B0 --> a_1(1260)+/- pi-/+ decays.

Abstract
This dissertation reports the measurement of the branching fractions of neutral and charged B meson decays to final states containing a K_1(1270) or K_1(1400) meson and a charged pion. The data, collected with the BaBar detector at the SLAC National Accelerator Laboratory, correspond to 454 million B Bbar pairs produced in e+ e- annihilation. We use the results to estimate the weak phase alpha from the time dependent CP asymmetries in B0 --> a_1(1260)+/- pi-/+ decays.File in questo prodotto:
