Abstract

The KTeV experiment has carried out a broad program of studies of rare kaon decays. In this paper we present results on K_L → π⁰γγ, K_L → π⁰e⁺e⁻γ and K_L → π⁰π⁰γ. These decays provide a window for testing chiral perturbation theory at O(p⁶). We find BR(K_L → π⁰γγ) = (1.30 ± 0.03) × 10⁻⁶, BR(K_L → π⁰e⁺e⁻γ) = (1.90±0.16±0.12)×10⁻⁸, and set the limit BR(K_L → π⁰π⁰γ) < 2.32×10⁻⁷. The KTeV measurements are competitive with or better than the world’s best results in these decays.
