Search for a Dark Higgs Boson Produced in Association with Inelastic Dark Matter at the Belle II Experiment
Belle II Collaboration, I. Adachi, L. Aggarwal +437
Inelastic dark matter models that have two dark matter particles and a massive dark photon can reproduce the observed relic dark matter density without violating cosmological limit…

Charged-hadron identification at Belle II
Belle II Collaboration, I. Adachi, H. Ahmed +408
The Belle II experiment's ability to identify particles critically affects the sensitivity of its measurements. We describe Belle II's algorithms for identifying charged particles…

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…
