Recent results from Belle IIPublic
The Belle II experiment at the SuperKEKB energy-asymmetric e+e− collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is 6×1035 cm−2s−1 and the Belle II experiment aims to ultimately record 50 ab−1 of data, a factor of 50 more than its predecessor. With this data set, Belle… |

Recent spectroscopy results from Belle and Belle IIPublic
The Belle experiment at the KEKB energy-asymmetric 𝑒+𝑒− collider accumulated dataset with integrated luminosity of 1/ab, including Upsilon(nS) on resonances, off-resonances, and Upsilon(5S) scan data. And the Belle II experiment is a substantial upgrade of the B factory facility, with much higher instantaneous luminosity and will accumulate 50/ab … |

Hadronic B decays at Belle and Belle IIPublic
The investigation of 𝐵-meson decays to charmed and charmless hadronic final states is a keystone of the Belle II physics program. It allows for theoretically reliable and experimentally precise constraints on the CKM Unitarity Triangle fit, and is sensitive to effects from non-SM physics. Results on branching ratios, direct CP-violating asymmetrie… |

Charm lifetime measurements at Belle IIPublic
Outstanding vertexing performance and low-background environment are key enablers of a systematic Belle II program targeted at measurements of charm hadron lifetimes. Recent results from measurements of D0 meson, D+ meson, and Λc baryon lifetimes from the Belle II data samples will be presented. These results are the most precise measurements to d… |

Lepton flavor universality at Belle and Belle IIPublic
The rate of semitauonic and electroweak penguin decays in the B sector show hints of lepton-flavor universality violation. Belle and Belle II data is well suited to probe such anomalies. The low-background collision environment along with the possibility of partially or fully reconstructing one of the two B mesons in the event offer high precision… |

Recent Belle II results on decay-time-dependent CP violationPublic
Measurements of decay-time dependent CP violation are chief goals of the Belle II physics program. Comparison between penguin-dominated b→qq ̅s and tree-dominated b→cc ̅s results allows for stringent tests of CKM unitarity that are sensitive to non-SM physics. This talk present first Belle II results on the mixing rate and lifetime of B^0 mesons, a… |

Recent results on the dark sector from Belle IIPublic
Belle has unique reach for a broad class of models that postulate the existence of dark matter particles with MeV—GeV masses. This talk presents recent world-leading physics results from Belle II searches for dark Higgstrahlung and invisible Z′ decays; as well as the near-term prospects for other dark-sector searches. |

Selective background Monte Carlo simulation at Belle IIPublic
The Belle II experiment, beginning data taking with the full detector in early 2019, is expected to produce a volume of data fifty times that of its predecessor. With this dramatic increase in data comes the opportunity for studies of rare previously inaccessible processes. The investigation of such rare processes in a high data volume environment… |

Semileptonic and rare decays at Belle IIPublic
Decays of B mesons that proceed through electroweak and radiative penguin amplitudes attract significant attention due to a number of observed discrepancies between the standard-model predictions and the results. Belle II is expected to perform measurements on channels closely related to those exhibiting anomalies and that are uniquely available t… |
