Findings
Measured sin2phi_1 value with improved precision
Determined B-meson lifetime accurately
Estimated Delta-m_d using three different methods
Abstract
We report results of proper-time evolution analyses of B decays at Belle, based on a 29.1/fb data sample recorded at the Upsilon (4S) resonance. These results include measurements of sin2phi_1, the lifetime of B-mesons, and the mass-difference between two mass eigenstates of the B^0-B^0-bar system (Delta-m_d). Delta-m_d is measured using three different methods: fully reconstructed hadronic modes, a fully reconstructed semi-leptonic mode, and a partially reconstructed D*+ pi- mode.
