Description

The Belle and Belle II experiments have collected a 1.1 ab$^{-1}$ sample of $e^+ e^-\to B\bar{B}$ collisions at a centre-of-mass energy corresponding to the $\Upsilon(4S)$ resonance. These data allow measurements of $CP\!$ violation and the Cabibbo-Kobayashi-Maskawa matrix elements in $B$-meson decay. In particular, we measure the $CP$-violating phase $\phi_1/\alpha$ and $\left|V_{cb}\right|$. In addition, we present constraints on the branching fractions of $B^+\to\ell^+\nu~(\ell=\mu,~\tau)$, which are related to $\left|V_{ub}\right|$.
