Measurement of the energy dependence of the , , and cross sections at Belle~II
Belle II Collaboration, I. Adachi, L. Aggarwal +466
We report measurements of the , , and cross sections at four energies, 10653, 10701, 10746 and 10805 MeV, using data collected b…

Measurement of asymmetries in decays at Belle II
Belle II Collaboration, I. Adachi, L. Aggarwal +450
We report a measurement of decay-time dependent charge-parity () asymmetries in decays. We use pairs collected at…

Search for a resonance in four-muon final states at Belle II
Belle II Collaboration, I. Adachi, K. Adamczyk +401
We report on a search for a resonance decaying to a pair of muons in events in the 0.212-9.000 GeV/ mass range, using 178 fb of…

Search for the and processes at
Belle II Collaboration, I. Adachi, L. Aggarwal +419
We search for the and processes at a center-of-mass energy of 10.745 GeV, which is close to the peak of the state. We use data…
