Results and Prospects for Radiative and Electroweak Penguin Decays at Belle IIPublic
In the recent years, several measurements of π΅-decays with flavor changing neutral currents, i.e. πβπ transitions hint at deviations from the Standard Model (SM) predictions. These decays are forbidden at tree-level in the SM and can only proceed via suppressed loop level or box diagrams. Rare decays of π΅ mesons are an ideal probe to search for phβ¦ |

Towards first ππ’π and πππ measurements at the Belle II experimentPublic
Precision determinations of ππ’π and πππ play a central role in precision tests of the CKM sector of the Standard Model and complement direct measurements of CP violation of B meson decays. In this talk, we present first studies towards measurements of |ππ’π| and πππ, with semileptonic decays using collision events recorded at the Ξ₯(4π) resonance byβ¦ |

Measurements of BβD(*)h and charmless B decays at Belle IIPublic
The CKM angle πΎ (π3) of the unitarity triangle is the only one that is accessible with tree-level decays in a theoretically clean way. The key method to measure πΎ is through the interference between π΅+βπ·0πΎ+ and π΅+βπ·Β―0πΎ+ decays that occurs if the final state of the charm-meson decay is accessible to both the π·0 and π·Β―0 mesons.
