Analysis of the rare B+ -> K+ nu nubar decay at Belle IIPublic
We search for the rare decay B+ -> K+ nu nubar in a 362 /fb sample of electron-positron collisions at the Upsilon(4S) resonance collected with the Belle II detector at the SuperKEKB collider. The branching fraction is predicted with high accuracy in the standard model (SM) and is enhanced in several SM extensions. We use the inclusive properties… |

Recent Belle II results in charm physicsPublic
Charm physics, involving a heavy up-type quark, offers a pathway to search for new particles and couplings beyond the Standard Model complementary to that of B physics. A program based on precision measurements of charm lifetimes is now underway at Belle II, and benefits from the detector's outstanding vertexing performance and low-background envi… |

Recent Belle II results on radiative and electroweak penguin decaysPublic
Decays of B mesons that proceed through radiative penguin amplitudes probe a large class of generic non-SM models for which Belle II has unique reach. We present recent results from an inclusive b->s,gamma analysis and a B->rho,gamma analysis. In addition, we report b->sll results on decays of B mesons, which proceed through electroweak penguin am… |

Recent quarkonium results at Belle IIPublic
Belle II offers unique possibilities for the discovery and interpretation of exotic multiquark states to probe the fundamentals of QCD. This talk presents recent results on searches for the hidden bottom transition between Y(10750) and chi_bJ, and measurements of the energy dependence of the e+e-=>B(*)Bbar(*) cross section. |

Recent time-dependent measurements of CP violation at Belle IIPublic
Time-dependent measurements of CP violation are chief goals of the Belle II physics program. Comparison between penguin-dominated b->qqbars and tree-dominated b->ccbars results allows for stringent tests of CKM unitarity that are sensitive to non-SM physics. This talk presents recent Belle II results on B0->Kspi0, B0->KsKsKs, and B0->phiKs decays. |

Recent Belle II results on hadronic B decaysPublic
The investigation of B-meson decays into charmed and charmless hadronic final states is a keystone of the Belle II program. It offers theoretically reliable and experimentally precise constraints on CKM unitarity, it is sensitive to effects from non-SM physics, and it furthers knowledge about uncharted b->c hadronic transitions. Recent results on … |

Recent dark-sector results at 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 Z` decays as well as long-lived (pseudo) scalars in B decays. |

Recent tau-lepton results at Belle and Belle IIPublic
Charged lepton flavor violation (CLFV) is forbidden in the Standard Model but possible in several new physics scenarios. Thus, the observation of CLFV would be a clear signature of new physics. We report the world-leading result of lepton-flavor-violating decays of \tau lepton decays into a light charged lepton (l = e,mu) and a vector meson using … |

Recent Belle II results on semitauonic decays and tests of lepton-flavor universalityPublic
The observed rate of semitauonic B decays has been consistently above expectations since these decays were first measured. Significant differences between the forward-backward asymmetry in B->D*enu and B->D*munu were also reported. Belle II data are well suited to probe these anomalies. The low-background collision environment along with the possi… |

Recent Belle II results on the CKM parameters |V_cb| and |V_ub|Public
Semileptonic B-meson decays allow for determining the magnitudes of the CKM matrix parameters Vcb and Vub, two fundamental parameters of the SM flavor sector. Belle II analyses use both exclusive decays such asB->D*lnu and B->pilnu, or inclusive X_clnu or X_ulnu final states restricted in phase space. The low-background collision environment, alon… |

Recent Belle II results on radiative and electroweak penguin decaysPublic
Radiative and electroweak penguin decays are excellent probes for new physics, since they are forbidden at tree level in the Standard Model, and hence any deviation from their predicted branching fractions would be a clear sign of physics processes not accounted for by the theory. In this paper, recent results on radiative and electroweak penguin … |
