Measurement of mixing-induced CP violation in the decay
Belle II Collaboration, M. Abumusabh, I. Adachi +437
Measurements of charge-parity (CP) violation in quark transitions provide stringent tests of the current theory and sensitive probes of particles or interactions beyond it. We repo…
Measurement of the lifetime
Belle II Collaboration, F. Abudinén, L. Aggarwal +360
An absolute measurement of the lifetime is reported using decays in events reconstructed from data collected by the Belle II experiment at t…
Radiation damage study of Belle II silicon strip sensors with 90 MeV electron irradiation
K. Adamczyk, H. Aihara, K. Amos +58
The silicon strip sensors of the Belle II silicon vertex detector were irradiated with 90 MeV electron beams up to an equivalent 1-MeV-neutron fluence of $3.0\times 10^{13}~{\rm n}…
Operational experience and performance of the Silicon Vertex Detector after the first long shutdown of Belle II
K. Ravindran, K. Adamczyk, H. Aihara +62
In 2024, the Belle II experiment resumed data taking after the Long Shutdown 1, which was required to install a two-layer pixel detector and upgrade accelerator components. We desc…
