Description

The Belle and Belle II B-factories have collectively gathered an extensive 1.1~ab${}^{-1}$ dataset of $e^{+}{e}^{-}$ collisions at the $\mathrm{{\rm Y}}(4S)$ resonance, resulting in the production of numerous $B\overline{B}$ pairs. This allows for precise measurements of hadronic $B$ decays, which is essential to test Quantum Chromodynamics (QCD) and refine theoretical models. This also helps improve simulation accuracy. We present results for the B to hadronic decays such as $B^{-}\to D^0{\rho }^{-}$, $B\to D{K}^{\ast }{K}_{(s)}^{(\ast )(0)}$, $B^0\to {\eta }^{\prime }{K}_S^0$ and $B\to {\pi }^0{\pi }^0$. These decays provide deep insights into absolute branching fractions and angular distributions of decay products and help measure CKM elements.
