Abstract
We investigate various mechanisms of enhancement of the branching ratios of the decay KL→π0l+l− as compared to the predictions of the Standard Model. We propose a model with several Higgs doublets, which contains a Higgs boson with nearly equal couplings to e+e− and µ+µ− pairs. In this model, the branching ratio BR (KL→π0e+e−, π0µ+µ−) can be close to the present experimental upper bounds.
