Description
We are searching for lepton flavor violating decays of ┬ → 3µ and ┬ → ρµµ using e+e− collision data recorded with the Belle experiment at KEK. In these modes, nearly 40% of low momentum muons are lost before reaching the dedicated identification device, called the KL and muon (KLM) detector. One of the main goals of our analysis has been how to recover these muons using information from the preceding non-KLM detectors, combined with a multivariate technique. In addition, we have taken part in the analysis of early Belle II commissioning data towards the re-discovery of various decays of charmonia and B mesons; this confirms that all Belle II sub-detectors are working fine. This talk will present the current status and future plans for the aforementioned studies.
