Studies of hadron spectroscopy at Belle and Belle IIPublic
The Belle and Belle~II experiments have collected a $1.4~\mathrm{ab}^{-1}$ sample of $e^+e^-$ collision data at centre-of-mass energies near the $\Upsilon(nS)$ resonances. These data include a 19.2~fb$^{-1}$ sample collected near the $\Upsilon(10753)$ resonance to probe its potentially exotic nature. We present several results related to the follo… |

TOP detector for particle identification at Belle IIPublic
The Time-Of-Propagation (TOP) counter is a ring-imaging Cherenkov detector designed to identify the charged hadrons in the barrel region of the Belle II detector. The Belle II experiment collected data delivered by the SuperKEKB accelerator from March 2019 to June 2022. After the first run period (Run1) a long shutdown (LS1) was dedicated to imple… |

Searches for LLP at Belle and Belle II Public
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 new long-lived particles in the mass range from a few MeV to 10~GeV. Belle II has searched for a long-lived scalar pa… |

Study of Xi* and other Hyperons at Belle/Belle IIPublic
The excited states of the Xi hyperons remain poorly understood due to limited experimental studies. In this presentation, we present our recent studies focusing on Xi and hyperon resonances at the Belle experiment. We aim to shed light on the properties of these states. Furthermore, we provide an overview of the current status of the Belle II expe… |

Semileptonic $B$ decays from Belle and Belle IIPublic
This proceeding summarizes recent measurements of the CKM matrix elements $|V_{cb}|$, $|V_{ub}|$, and lepton-flavor universality tests in semileptonic B decays from the Belle and Belle~II experiments. The decay branching factions $R(D^{*})$ and $R(X)$ are measured with the Belle~II early dataset and the results are found to be consistent with the … |

The Belle II Detector Upgrades Framework Conceptual Design ReportPublic
We describe the planned near-term and potential longer-term upgrades of the Belle II detector at the SuperKEKB electron-positron collider operating at the KEK laboratory in Tsukuba, Japan. These upgrades will allow increasingly sensitive searches for possible new physics beyond the Standard Model in flavor, tau, electroweak and dark sector physi… |

B decays at e+/e- collidersPublic
The rare decays of B mesons offer a prime opportunity to test predictions of the Standard Model (SM) and to search for effects beyond the SM. The coherent production of B mesons at e+e− colliders provides a clean experimental setup for these studies. |

Recent B Physics results from Belle and Belle IIPublic
The Belle II experiment has collected a 424 fb−1 sample of 𝑒+𝑒− collisions produced by the asymmetric SuperKEKB collider. Ninety percent of the sample is at the Υ(4𝑆) resonance, which decays to 𝐵-meson pairs. The predecessor experiment, Belle, collected nearly 1 ab−1 of data from 1999-2010, three-quarters of which was at the Υ(4𝑆). From these Υ(4𝑆… |

Charm results 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 centreof-mass energies near the Υ(nS) resonances. These samples contain a large number of e +e − → cc¯ events that produce charmed mesons. Direct CP violation is searched for in D0 → K0 SK0 S decays and D-meson decays to a four-body final state. For the… |

Amplitude analysis of tau -> 3pi at Belle (II)Public
We present a partial-wave analysis of $\tau^-\to \pi^-\pi^-\pi^+ \nu_\tau$ decays using the world`s largest sample of these decays from the Belle experiment at KEK, Japan. We discuss the employed covariant tensor formalism and the treatment of large incoherent backgrounds in our sample. We give preliminary results on light-meson resonances appeari… |
