Contribution

It provides new experimental data on various B decay modes, enhancing understanding of CP violation and decay dynamics within the Standard Model framework.

Findings

Measured branching fractions for multiple decay modes.

Observed CP asymmetries consistent with Standard Model predictions.

Analyzed polarization amplitudes in vector-vector decays.

Abstract

We present recent results from the Belle experiment on rare hadronic B meson decays. The results are based on a 78 fb^{-1} data sample and consist of branching fractions, CP asymmetries, and polarization amplitudes. The decays studied include two-body pseudoscalar-pseudoscalar final states (B -> pi pi, K pi, KK, and D^0 K^\pm); pseudoscalar-vector final states (B -> omega pi, omega K, and phi K); and vector-vector final states (B -> phi K* and rho^+ rho^0).
