Sažetak

We analyse K → nnnγ decay in tne framework of a chiral Lagrangian supplemented by the 1/N expansion. This process is dominated by the inner bremsstrahlung emission. The basic process K → nnnγ is well described within the chiral Lagrangian approach. It is necessary to introduce the higher-order interactions in order to obtain result close to the experimental one. In addition to the dominant part of the amplitude we determine direct emission part. For the calculation of decay width we make the cut in photon energy and obtain result in agreement with the experiment.
