We search for the lepton flavor-violating T + ~7 decay using 29.7 million T pairs accumulated by the Belle experiment. The main background sources are found to be r pairs with r + ~YU decay and radiative pp events. One event is observed in the signal region, while 2.5 f 0.6 background events are exp
