Description

Charmless $B$ decays provide a unique portion of the Belle II program. The expected large signal yields with moderate backgrounds associated with efficient reconstruction of neutral particles 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 65 fb$^{-1}$ of integrated luminosity. Results include a test of the $K\pi$ isospin sum-rule, an angular analysis of $B \to \rho^+ \rho^0$ decays, and the reconstruction of a $B^0 \to \pi^0\pi^0$ signal.
