WG4: Measurement of sin2phi and sin2phieff at Belle/Belle II (including lifetime and oscillation frequency)Public
Belle II has started to produce time-dependent CP violation results. We report six results in total, which are unique and world-leading with the improved analysis tools. |

WG2: LFU tests at Belle / Belle IIPublic
This talk reviews measurements of R(D*) and R(X) and R_e/mu(X) from Belle II, of R_e/mu(D*) from Belle, and of LFU-sensitive angular asymmetries from both Belle and Belle II. |

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… |

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 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 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 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
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 program requires excellent vertexing capabilities. After presenting recent world-l… |

The new Belle II charm flavor taggerPublic
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. Measurements of CP violation and mixing play a key role in this program. We present a novel algorithm that identifies the flavor of neutral charm mesons at the time of production. … |

Charm physics prospects at the Belle II experimentPublic
The Belle II experiment is a substantial upgrade of the Belle detector and will operate at the SuperKEKB energy-asymmetric $e^+ e^-$ collider. The accelerator has already successfully completed the first phase of commissioning in 2016 and first electron-positron collisions in Belle II are expected for April 2018. The design luminosity of SuperKEKB… |

Studies of mesons in Quark Model and beyond: from Belle to Belle IIPublic
We give a review of selected results on meson studies at Belle. Mechanisms of meson production are presented for conventional light and heavy mesons as well as for so called XYZ states. Examples of new states discovered at Belle are given. Also discussed are expectations for future experiments at Belle II. |

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, primarily required to install the new two-layer DEPFET detector (PXD) and upgrade components of the accelerator. In May 2023 the whole silicon tracker (VXD) was extracted from Belle II and the new VXD commissioning phase began to be ready to take data by t… |
