Description

We investigate the CP violating contribution to the decay mode KL→π0e+e- in the standard model. We present a recalculation of the effective lagrangian involving only light quarks, working to all orders in mt/mW and computing the leading order strong interaction corrections. We consider the standard model prediction for the branching ratio as a function of top quark mass and KM parameters, and briefly consider nonstandard model contributions to this decay. (orig.)
