We consider the rare decay K± → π± π0 e+ e− currently under analysis by the NA62 Collaboration. A new theoretical approach for the differential decay width has been performed. We compared the dependencies of the differential decay rate with respect to dilepton and dipion system masses in different theoretical descriptions.
