Abstract | The physics of charmless $B$ decays is an unique portion of the Belle II program. Expected large signals over moderate backgrounds, associated with efficient reconstruction of neutral particles, will enable world-leading determination of the CKM phase $\alpha/\phi_2$, a conclusive understanding of the so-called K-$\pi$ CP puzzle, and further insight into the nature of localized CP violation in three-body decays. We report preliminary measurements based on the sample collected during 2019-2020 operations and corresponding to 63 fb$^{-1}$ of integrated luminosity. Results include a test of the $K\pi$ isospin sum-rule, and an angular analysis of $B \to \rho^+ \rho^0$ decays. |
