الوصف: We report measurements of the branching fraction and $CP$ asymmetry in $B^{0} \to \pi^{0} \pi^{0}$ decays reconstructed at Belle II in an electron-positron collision sample containing $198 \times 10^{6}$$B\overline{B}$ pairs. We measure a branching fraction $\mathcal{B}(B^0 \rightarrow \pi^0 \pi^0) = (1.38 \pm 0.27 \pm 0.22) \times 10^{-6}$ and a $\it CP$ asymmetry $\mathcal{A}_{\rm CP}(B^0 \rightarrow \pi^0 \pi^0) = 0.14 \pm 0.46 \pm 0.07$, where the first uncertainty is statistical and the second is systematic.
