Recent results at Belle IIPublic
The Belle II experiment at the SuperKEKB energy-asymmetric e+e- collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is 6Γ10^35 cm-2s-1 and the Belle II experiment aims to ultimately record 50 ab-1 of data, a factor of 50 more than its predecessor. With this data set, Bellβ¦ |

Recent Belle II results on the CKM parameters $|V_{cb}|$ and $|V_{ub}|$Public
emileptonic π΅ decays allow to determine the magnitudes of the CKM matrix parameters |πππ| and |ππ’π|, two fundamental parameters of the standard model flavor sector. At Belle II these measurements use both exclusive decays such as π΅βπ·ββπ and π΅βπβπ, or inclusive ππβπ or ππ’βπ final states restricted in phase space. The low-background collision enviroβ¦ |

Recent quarkonium results at Belle IIPublic
Belle II offers unique possibilities for the discovery and interpretation of exotic multiquark combinations to probe the fundamentals of QCD.This talk present recent results on the amplitude analysis of the charmonium-like state π(3940) and searches for the hidden bottom transition between π(10750) and πππ½. |

Recent Belle II results on decay-time-dependent CP violationPublic
Measurements of decay-time dependent CP violation are chief goals of the Belle II physics program. Comparison between penguin-dominated πβππΒ―π and tree-dominated πβππΒ―π results allows for stringent tests of CKM unitarity that are sensitive to non-SM physics. This talk present first Belle II results on the mixing rate and lifetime of π΅0 mesons, an β¦ |

Recent Belle II results on electroweak penguinsPublic
Decays of B mesons that proceed through electroweak penguin amplitudes attract significant attention due to a number of observed discrepancies between the standard-model predictions and the results. Belle II is expected to perform measurements on channels closely related to those exhibiting anomalies and that are uniquely available to Belle II. Th⦠|

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 MeVβGeV masses. This talk presents recent world-leading physics results from Belle II searches for dark Higgstrahlung and invisible πβ² decays; as well as the near-term prospects for other dark-sector searches. |

Recent tau-lepton results at Belle IIPublic
The low-background environment of electron-positron collisions along with the large expected sample size and an hermetic detector make Belle II the premier experiment for studying tau-lepton physics. This talk presents recent world-leading physics results from Belle II searches for tau decays into a scalar non-SM particle and a lepton. Perspective⦠|

Semileptonic and leptonic decays with tau at the Belle II experimentPublic
Semileptonic and leptonic decays with $\tau$ are a stringent test of the Standard Model and an excellent probe for new physics. In this talk, an overview of the status of such measurements at the Belle II experiment is given. Future prospects for several golden semitauonic channels are also discussed. |

Recent Belle II results on hadronic B decaysPublic
The investigation of π΅-meson decays to charmed and charmless hadronic final states is a keystone of the Belle II physics program. It allows for theoretically reliable and experimentally precise constraints on the CKM Unitarity Triangle fit, and is sensitive to effects from non-SM physics.

Recent Belle II results on semitauonic decays and tests of lepton-flavor universalityPublic
The rate of semitauonic π΅ decays has been consistently above theory expectations since these decays were first measured. Recently significant differences between the forward-backward asymmetry in π΅βπ·βππ and π΅βπ·βππ were also reported. Belle II data is well suited to probe such anomalies.

Measurement of charm lifetimes at Belle IIPublic
Outstanding vertexing performance and low-background environment are key enablers of a systematic Belle II program targeted at measurements of charm hadron lifetimes Recent results from measurements of π·0 meson, π·+ meson and Ξπ baryon lifetimes are presented. The results are the most precise to date. |
