Abstract
The rare decay KL→e+e-e+e- proceeds via a two-virtual-photon intermediate state with internal photon conversions to e+e- pairs. A measurement of the branching ratio of the rare decay at the Fermilab experiment is reported. In addition, a study of CP symmetry in this decay and the first analysis of a KLτ*τ* form factor is presented.
