Heavy Quarkonia and Multiquarks at B-factoriesPublic
This review will cover the most recent results from the B factories in the field of heavy quarkonia and multiquark systems. At Belle-II, the first data taking period beyond the $\Upsilon(4S)$ peak energy has been been devoted to the study of the region around $\sqrt{s}=10.75$ GeV, where enhanced transition rates to lower bottomonia suggested the e… |

A model-independent likelihood function for the Belle II B+ -> K+νν analysisPublic
Rare decays like B+ -> K+νν, searched for by the Belle II collaboration, are important in particle physics research as they offer a window into physics beyond the Standard Model. However, the experimental challenges induced by the two final state neutrinos require assumptions on the kinematic distribution of this decay. Consequently, the results … |

Recent results from the Belle II experimentPublic
The Belle II experiment at the SuperKEKB asymmetric-energy electron-positron collider has been collecting the world’s highest-intensity collisions at the (4S) since 2019. A data set comparable in size to that of predecessor experiments, and collected with the new detector, enables unique or world-leading results. Examples include indirect searches… |

Recent Belle II results on time-dependent CP violation and charm physicsPublic
Measurements of time dependent CP violation are chief goals of the Belle II physics program. Comparisons of penguin-dominated $b\to sq\bar{q}$ to tree-dominated $b\to sc\bar{c}$ results allow for stringent tests of CKM unitarity that are sensitive to non-SM physics, but require excellent vertexing capabilities. After presenting recent world-leadi… |

Dark matter search at BellePublic
This is a presentation showing results produced by the Belle experiment on searches for an extra gauge boson, Z`, and for the scalar (leptophylic dark Higgs). We cover the previous result by Belle for the Z` search and also give the most recent progress on the Z` invisible decay mode. |

Search for (pseudo-)scalar and long-lived particles at Belle IIPublic
Belle II 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 results from searches for scalar and long-lived particle at Belle II and the sensitivity to probe more DM models. |

The Silicon Vertex Detector of the Belle II ExperimentPublic
In June 2022 the data taking of the Belle II experiment was stopped for the Long Shutdown 1 (LS1), which is primarily required to install a new two-layer DEPFET detector (PXD) and upgrade components of the accelerator. The whole silicon tracker (VXD) will be extracted from Belle II, then the outer four-layer doublesided strip detector (SVD) is spl… |

Machine Learning for New Physics Searches in B → K∗0 µ+µ− DecaysPublic
We report the status of a neural network regression model trained to extract new physics (NP) parameters in Monte Carlo (MC) simulation data. We utilize a new EvtGen NP MC generator to generate B → K∗0 µ+µ− events according to the deviation of the Wilson Coefficient C9 from its SM value, δC9 . We train a three-dimensional ResNet regression model, … |

Search for Inelastic Dark Matter with a Dark Higgs at Belle IIPublic
Belle II has a unique reach for a broad class of models that postulate the existence of dark matter particles in the MeV-GeV mass range. One highly motivated scenario is a model which involves inelastic dark matter, consisting of two dark matter states with a mass splitting between them and the presence of a dark Higgs boson. This model has a sign… |

WG3: b -> s/d gamma at Belle/Belle IIPublic
Rare decays of B mesons to radiative final states serve as an ideal ground to search for New Physics effects from short range contributions. Being one of the first transitions of the electroweak penguin family to be observed by CLEO in the early 90s, these transitions serve an important role in testing the predictions of the Standard Model. In thi… |
