Recent quarkonium results at Belle IIPublic
Belle II offers unique possibilities for discovering and interpreting exotic multiquark bound states to probe the fundamentals of QCD. This talk presents recent results on a unique data set collected at energies above the Υ(4S), including searches for the hidden bottom transition between Y(10750) and 𝜒𝑏𝐽. |

Recent dark-sector results from Belle IIPublic
The Belle II experiment at the SuperKEKB collider has unique sensitivity to 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 long-lived scalar particles and Z’ decays; as well as the near-term prospects for other dar… |

Recent results related to anomalies at Belle IIPublic
In recent years, discrepancies from standard-model predictions, which suggest violation of lepton-flavor universality, have emerged in multiple measurements of B meson decays. This talk reports on related, recent Belle II results on lepton-flavour universality and long-lived particles. |

Recent highlights from the Belle II experimentPublic
The Belle II experiment at the SuperKEKB collider has now collected approximately 400 million bottom-antibottom meson pairs at the Y(4S) resonance. We report a selection of recent results in bottom, charm and tau-lepton physics that probe non-standard-model dynamics and refine our understanding of the electroweak and strong interactions. |

Recent Belle II results related to flavor anomalies Public
In this talk recent results from Belle II on flavor anomalies in semi-leptonic B-decays will be discussed. We will focus on the first inclusive test R(X) for LFU in light leptons and on a new LFU test exploiting angular asymmetries in B->D*lnu decays. |

Overview of the Belle II physics progam (focus on heavy flavor)Public
Will present overview of Belle II physics with a focus on heavy flavor. This will include a detailed discussion of a sample of world-leading new results in lepton flavour violation in semileptonic decays, asymmetries in angular observables in B->D*l nu decays, a search for tau -> e/mu alpha decays and a tau mass measurement. These will demonstrate… |

$R(D^{*})$ measurement using the hadronic tag algorithm with $189~\mathrm{fb}^{-1}$ data at the Belle~II experimentPublic
In the semileptonic decay of 𝐵 mesons, the global average of $R(D^{*})$ measurement deviates from the Standard Model by more than $3\sigma$. It indicates a violation of the lepton universality. We will measure $R(D^{*})$ for the validation of this deviation using the Belle II data. We have developed an analysis method employing the hadronic tag al… |

Belle II results related to b→c anomaliesPublic
Recent Belle II results of light-lepton flavor universality tests for b→c anomalies using semileptonic B decays are shown. This talk discusses the results of two measurements of $R(X_{e/\mu})$ and asymmetries of five angular observables between electron and muon, $\Delta\mathcal{A}_{x}(w)$, involving the hadronic tagging method in the Full Event I… |

Study of B+ → J/ψ K*+ (→KS pi+) decaysPublic
We report a study for reconstruction of the decay chain of B0 → J/ψK∗+ followed by J/ψ → μ+μ−, K∗+ → KS0π+ and KS0 → π+π−. The vertex displacement in the same decay where the signal B+ vertex is reconstructed using all the available tracks or using only the tracks coming from KS0 gives an opportunity to investigate possible Data/MC difference in t… |

Particle identification at Belle II using Neural NetworksPublic
We will present improvements to the charged-particle identification algorithms used by the Belle II experiment located at KEK, Japan. So far, different approaches have been used to tackle the challenge of combining the information from each subdetector into a single variable for particle identification in an optimal way. We will present evaluation… |

BSM Discovery Potential of Belle II in b->c and b-->sPublic
We describe the BSM discovery potential of Belle II@SuperKEKB in b->c and b->s processes. We review the Belle II prospects presented at Snowmass 2022 and then describe three pathways for discovery of new physics. These are (1) Angular correlations in B->D* l nu (2) Angular correlations in B->K* l+ l- and (3) B->K(*) nu nubar. |
