The Belle and Belle II B-factories have collectively gathered an extensive 1.1 ab \(^{-1}\) dataset of \(e^+ e^-\) collisions at the \(\Upsilon (4S)\) resonance, resulting in the production of numerous \(B\bar{B}\) pairs. This allows for precise measurements of hadronic B decays, 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 \(B^- \rightarrow D^0 \rho ^-\) , \(B \rightarrow DK^{*}K_{(s)}^{(*)(0)}\) and the first Belle and Belle II combined \(\phi _3\) measurement.

摘要

The Belle and Belle II B-factories have collectively gathered an extensive 1.1 ab \(^{-1}\) dataset of \(e^+ e^-\) collisions at the \(\Upsilon (4S)\) resonance, resulting in the production of numerous \(B\bar{B}\) pairs. This allows for precise measurements of hadronic B decays, 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 \(B^- \rightarrow D^0 \rho ^-\) , \(B \rightarrow DK^{*}K_{(s)}^{(*)(0)}\) and the first Belle and Belle II combined \(\phi _3\) measurement.
