Abstract: With the start of data taking using the Belle II detector at the SuperKEKB electron-positron collider a new era in searches for New Physics is on the horizon. We report here on plans and first Monte Carlo studies to search for lepton flavor violation (LFV) in tau leptons. In particular, we investigate the decay τ−>l π0, which is highly forbidden in the Standard Model, but could possibly become observable in certain scenarios of New Physics. Using the improved detector capabilities of Belle II, estimates of the efficiency and backgrounds for the above LFV decay are presented.
