Latest results from Belle and Belle IIPublic
In this invited plenary talk, we report recent results based on the e+e- collision data recorded by the Belle II experiment and the legacy data from its predecessor (Belle), both at the KEK laboratory of Japan. These would include the study of CP violation in B and D meson decays, search for suppressed decays of B and D mesons and tau leptons, as … |

Light dark matter searches at (Super) B-FactoriesPublic
The B-Factories Belle and BaBar provided an excellent environment to search for light mediators in the GeV mass range at e+e- colliders. I will first give an overview of the searches at Belle and BaBar. In the second part I will describe the sensitivity and first results of the Super B-Factory Belle II that started data taking in 2019. With dedica… |

Dark sector searches at Belle IIPublic
The Belle II experiment at the asymmetric 𝑒+𝑒− collider, SuperKEKB, is a substantial upgrade of the Belle/KEKB experiment. Belle II aims to record 50 ab−1 of data over the course of the project. During the first physics runs in 2018-2020, around 100 fb−1 of data were collected. These early data include specifically-designed low-multiplicity trigge… |

Charmless B decays at Belle IIPublic
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 𝛼/𝜙2, a conclusive understanding of the so-called K-𝜋 CP puzzle, and further insight into the nature of loc… |

Search for a visible Z0 dark boson in mumutautau final state with Belle IIPublic
The Standard Model (SM) of particle physics is currently the best known description of the fundamental constituents of matter and their interactions. However, among other things, it cannot explain the existence of dark matter, and some experimental results deviate from SM predicitons, suggesting the possibility of including New Physics by extendin… |

Searches for muonic dark forces at Belle IIPublic
In this presentation, I will talk about the prospects to search for a muonic dark force at Belle II in events with four muons in the final state. These events could be due to a new gauge boson Z′ which couples only to the second and third lepton family. A short description of the background suppression technique, based on artificial neural network… |
