Identification of pions and muons with the Belle II calorimeter using convolutional neural networkPublic
The Belle II experiment is located at the asymmetric SuperKEKB e+e- collider in Tsukuba, Japan. The electromagnetic calorimeter (ECL) in Belle II is designed to reconstruct neutral particles. Additionally, the ECL can identify charged particles e.g. electrons, muons and pions. Identification of low-momenta muons and pions in the ECL is crucial if … |

Prospects of the new physics search at Belle II by precise measurements of the CKM matrix elementsPublic
In Standard Model, CKM matrix describes the quark coupling strength with weak interaction, as the determination on the elements is always an important field in flavor physics. Deviation from the unitarity of the matrix can be an indication to physics beyond the Standard Model. Measurements on various B decay mechanisms provide experimental constra… |

Muon and electron identification efficiencies and hadron-lepton mis-identification rates at Belle II for Moriond 2022Public
We present a collection of selected results on the performance of Belle II in the identification of electrons and muons. This work is carried out using data collected at the Belle II experiment from 2019 to mid-2021.

CMOS Upgrade to the Belle II Vertex DetectorPublic
CMOS Upgrade to the Belle II Vertex Detector* The success of the Belle II experiment at KEK (Japan) relies on the very high instantaneous luminosity, close to 6x10^35 cm^-2 s^-1, expected from the SuperKEKB collider. The beam conditions to reach such luminosity levels generate a large rate of background particles in the inner detection layers of B… |
