Measurements of hadronic $B$ decay rates at Belle and Belle IIPublic
The Belle and Belle~II experiments have collected a 1.1~ab$^{-1}$ sample of $e^+ e^-\to B\bar{B}$ collisions at the $\Upsilon(4S)$. The study of hadronic $B$ decays in these data allow the precise measurement of absolute branching fractions and angular distributions of the decay products. These measurements provide tests of QCD and enable the gene… |

Mixing and CP-violation measurements with $D$ mesons at Belle and Belle IIPublic
The Belle and BelleII experiments have collected a 1.4ab-1 sample of e+e- collision data at centre-of-mass energies near the Y(nS) resonances. These samples contain a large number of e+e- -> ccbar events that produce charmed mesons. We present searches of direct CP violation in several four-body decay modes. Asymmetries in the distributions of tri… |

Studies of hadron spectroscopy at Belle and Belle IIPublic
We review results on h_b(2P) decays to spin-triplet states (Belle), confirmation of Y(10753) using the e+e- --> Y(nS)pi+pi- processes (Belle II) and evidence for the P_cs(4459) pentaquark in inclusive Y(1S,2S) decays (Belle). |

Measurement of the $e^+e^-\to \pi^+\pi^-\pi^0$ cross section in the centre-of-mass range 0.62 to 3.5$~$GeV at Belle IIPublic
We report a measurement of the e^+e^- -> pi^+ pi^- pi^0 cross section in the energy range from 0.62 GeV to 3.5 GeV using an initial-state radiation technique. We use an e^+e^- data sample corresponding to 191 fb^-1 of integrated luminosity, collected at a centre-of-mass energy at or near the Y(4S) resonance with the BelleII detector at the SuperKE… |

Measurements of radiative and electroweak penguin $B$ decays without missing energy at Belle and Belle IIPublic
The Belle and Belle II experiments have collected a 1.1 ab$^{-1}$ sample of collisions at the resonance. We present results on the radiative decays $B^0 \rightarrow \gamma \gamma$, $B \rightarrow \rho \gamma$ and $B \rightarrow K^* \gamma$. CP and isospin asymmetries are presented for the latter two decays We also present results from decays invol… |

Rare and baryonic decays of charmed hadrons at Belle and Belle IIPublic
The Belle and Belle II experiments have collected a 1.4 ab-1 sample of e+e- collision data at centre-of-mass energies near the Upsilon(nS) resonances. These samples contain a large number of e+e- -> ccbar events that produce charmed mesons and baryons. We present searches for rare flavour-changing neutral current c->ul+l- processes in several deca… |

Measurements of $V_{cb}$ and $V_{ub}$ at Belle and Belle||Public
The Belle and Belle II experiments have collected a 1.1 ab$^{-1}$ sample of collisions at the $\Upsilon$(4S) resonance. These data, with low particle multiplicity and constrained initial state kinematics, are an ideal environment to study semileptonic and leptonic decays of the $B$ meson. Combined with theoretical inputs, measurements of both incl… |

The Belle and Belle II experiment have collected samples of e+ e- collision data at centre-of-mass energies near the Upsilon(nS) resonances. These data have constrained kinematics and low multiplicity, which allow searches for dark sector particles in the mass range from a few MeV to 10 GeV. Using a 426/fb sample collected by Belle II, we search f… |

Charm Meson Decays at Belle IIPublic
Charm physics, which involves a heavy up-type quark, offers a unique environment in which to search for new particles and couplings beyond the Standard Model. Studies with charmed hadron decays complement those in B physics, expanding the potential to observe BSM phenomena. The Belle II experiment has an active charm physics program that includes … |

Recent highlights from the Belle II ExperimentPublic
The Belle II detector began data collection in 2019 with the objective of surpassing the physics achievements of its predecessor, Belle, which amassed about 1 ab^−1 of integrated luminosity from e+e− collisions at a center of mass energy corresponding to (or near) the mass of the Υ(4S) resonance. In this talk, we present results derived from a por… |
