The Silicon Vertex Detector of the Belle II experimentPublic
The Belle II experiment located at KEK, Japan takes data from asymmetric e+e- collision provided by the SuperKEKB accelerator. The Silicon Vertex Detector (SVD), which is part of the Belle II Vertex Detector (VXD), has been operating smoothly and reliably since the start of data taking from March 2019. In this article, we report on the perfor… |

The Belle II Detector Upgrades 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 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 physics that are both complementary to … |

Recent Belle II results on the CKM parameters $|V_{cb}|$ and $|V_{ub}|$Public
In this talk, the latest measurements of $|V_{ub}|$ and $|V_{cb}|$ by the Belle II collaboration are presented. These results are based on 189 fb$^{-1}$ of Belle II data recorded at the $\Upsilon(4S)$ resonance. We report measurements with inclusive and exclusive $B$ decays. Two main strategies are employed for these results, one where the other … |

Recent results on charmed baryons from BellePublic
Charmed baryon spectroscopy can provide unique insights into QCD at low energies. The large data sample accumulated by the Belle experiment at the KEKB asymmetric energy e^{+}e^{-} collider enables new opportunities to study charmed baryons. We present recent measurements of charmed baryons at Belle, including studies of Omega_c -> Xi pi, Xi K and… |

Quarkonium/QCD results at Belle IIPublic
This proceeding summarizes recent discoveries and interprets exotic multiquark-bound states to probe the fundamentals of QCD at the Belle and Belle II experiments. The results are on a unique data set collected at energies higher than Υ(4S), including searches for the hidden bottom transition between Υ(10750) and 𝜒_𝑏𝐽. |

Belle II track finding and hit filtering using precise timing informationPublic
The SuperKEKB accelerator and the Belle II experiment constitute the second-generation asymmetric energy B-factory. SuperKEKB has recently set a new world record in instantaneous luminosity, which is anticipated to further increase during the upcoming run periods up to . An increase in luminosity is challenging for the track finding as it comes at… |

Exotic Hadron Spectroscopy at Belle and Belle IIPublic
Since the discovery of X(3872), Belle has been pioneering the exploration of tetraquarks, QCD bound states beyond standard mesons and baryons. More than a decade after the end of data taking, the Belle datasets are still producing results in hadron spectroscopy, and have provided the motivations for the first energy scan above the energy of the pe… |
