Abstract

We have searched for the K⁺→π⁺γγ decay in the kinematic region with π⁺ momentum close to the end point. No events were observed, and the 90% confidence-level upper limit on the partial branching ratio was obtained, B(K⁺→π ⁺γγ,P>213 MeV/c)<8.3×10^-9 under the assumption of chiral perturbation theory including next-to-leading order "unitarity" corrections. The same data were used to determine an upper limit on the K⁺→π⁺γ branching ratio of 2.3×10^-9 at the 90% confidence level.
