Recent results from 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 6×10^35 cm^−2 s^−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, … |

The Silicon Vertex Detector of the Belle II ExperimentPublic
The Belle II experiment is taking data at the asymmetric Super-KEKB collider, which operates at the Y(4S) resonance. The vertex detector is composed of an inner two-layer pixel detector (PXD) and the silicon vertex detector (SVD), made of four layers of double-sided silicon strip detectors. The SVD standalone tracking allows the reconstruction an… |

Latest results on semileptonic and electroweak penguin decays at Belle IIPublic
The Belle~II Collaboration presents four new analyses: The measurement of $V_{ub}$ from $B \to \pi e \nu_e$ decays with a fit to the differential $q^2$ spectrum, the determination of $V_{cb}$ using a fit to the differential $w$ distribution from $B^0 \to D^{\ast -} \ell^+ \nu_\ell$ decays, and the measurement of $q^2$ moments in inclusive $B \to X… |

Results related to anomalies at Belle IIPublic
Decays of B mesons that proceed through electroweak and radiative penguin amplitudes currently attract significant attention due to a number of observed discrepancies between the standard model predictions and the experimental results. Belle II is expected to perform measurements on channels closely related to those exhibiting anomalies and that a… |

Quarkonium at Belle IIPublic
The Belle II experiment at the SuperKEKB energy-asymmetric 𝑒+𝑒− collider is an upgrade of the B factory facility at KEK in Tsukuba, Japan. The experiment began operation in 2019 and aims to record a factor of 50 times more data than its predecessor. Belle II is uniquely capable of studying the so-called "XYZ" particles: heavy exotic hadrons consis… |

Prospects of |Vub| measurement at Belle IIPublic
Belle II is a B-factory experiment and thus offers a perfect environment for measuring the CKM-matrix element |Vub|. This measurement is particularly important for a precise test of the unitarity condition. Two types of measurement exist to extract |Vub|, both relying on semi-leptonic decays of B mesons: the exclusive measurements (where a particu… |

Belle II experiment: Status and prospect”Public
The Belle II experiment at the SuperKEKB 𝑒−𝑒+ collider is the successor to the Belle experiment. The design luminosity is 6.5 × 1035cm−2s−1 and it aims to record integrated luminosity of 50 fb−1 which is 50 times more than that of Belle. The current integrated luminosity has so far reached 213 fb−1 by summer 2021. Belle II aims to measure the matr… |

Charm and time-dependent CPV in B decays at Belle IIPublic
The Belle~II measurements relying on the precise determination of the positions of displaced vertices are presented. It is the analysis of the $B^0-\bar{B}^0$ mixing and CP violation based on the early Belle~II data and the $D^0$ and $D^+$ lifetime measurement, where the world-leading accuracy was achieved already with the analysed data set.

Study of photon energy bias using π0 → γγ decays from D∗+ → D0(→ K−π+π0)π+Public
We reconstruct clean samples of π0 → γγ decays from the D∗+ → D0(→ K−π+π0)π+ decay chain in both data and simulation to study the bias in the reconstructed π0 mass. We use the data collected by Belle II during 2019, 2020 and the first half of 2021 which correspond to 207 fb−1 of integrated luminosity. The results from the data are compared to run-… |
