Description
Summary:碩士 === 國立臺灣大學 === 物理研究所 === 93 === We report improved measurements of two bodies hadronic B meson to psudoscalar-vector decays with a ω meson in the final state using data collected with the Belle detector at KEKB asymmetric-energy e+e- collider located at the High Energy Accelerator Research Organization, Tsukuba, Japan. We measure the branching fractions of B+/- to ωK+/-, B+/- to ωπ+/-, and B0 to ωK0 at the same time, and most important of all, the direct C (charge) P (parity) asymmetries for the first two modes. Also, we search for the decays B0 to ωπ0 and B0 to ωη, where both the sub-decay channels: η to γγ and η to π+π-π0 are considered.
