摘要：

The decay K-L --> gamma nu nu is analyzed within the standard model. Short-distance contributions are found to dominate, yielding a branching ratio of similar to 0.7 x 10(-11). We examine the possibility that nonstandard model effects might be observed at higher rates. As an example, we calculate the branching ratio for the process mediated by neutral horizontal gauge bosons. Notwithstanding some model uncertainties, experimental limits for lepton number violation constrain these contributions to less than or similar to 2 x 10(-11).
