Measurements of the mass difference and the energy dependence of the cross-section ratio at Belle and Belle II

Belle, Belle II Collaborations, : +396

Using data samples collected by the Belle and Belle II experiments at the resonance with integrated luminosities of 571 fb and 365 fb, respectively, we measur…

Search for lepton-flavor-violating decays at Belle and Belle II

Belle, Belle II Collaborations, : +419

We present the results of a search for charged-lepton-flavor violating decays , where is either an electron or a muon. We combine $e…
