摘要：

We analyze K --> pi pi gamma decays in the framework of Chiral Perturbation Theory. We study the different Dalitz plot distributions, trying to find regions where o(p(6)) contributions could be more easily detected. To fulfill this program we compute all the o(p(4)) loop and counterterm contributions, finding a substantial agreement with the existing calculations and adding some small missing terms in K-S --> pi(+) pi(-) gamma.
