Experimental search for the decay mode KL -> pi0 gamma e+ e-
Abstract
We report on results of a search for the decay mode KL -> pi0 gamma e+ e- conducted by the E162 experiment at KEK. We observed no events and set a 90% confidence level upper limit of Br(KL -> pi0 gamma e+ e-)< 7.1x10-7 for its branching ratio. This is the first published experimental result on this decay mode.
