Abstract |
This proceeding summarizes recent measurements of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements and at the Belle and Belle~II experiments. It provides insights derived from both exclusive and inclusive determinations. Preliminary results from Belle~II are discussed, focusing on and utilizing data collected at the resonance. This reveals the derived branching fractions and . The shape measurement of at Belle extracted employing new lattice-QCD calculations as input and provided additional tests on the universality of light lepton flavors. In the realm of inclusive decay, the measurement for and the differential spectra of decays have been performed. This presentation also encapsulates the new analyses of and ratios. |
