Description

We investigate the CP violating contribution to the decay mode KL → π0 e+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 argue that this calculation is sufficient for a prediction at leading order in chiral perturbation theory. We predict the branching ratio as a function of the top quark mass and KM parameters, and briefly consider nonstandard model contributions to this decay. (author)
