Abstract

As first observed by the NA48/2 experiment at the CERN SPS, the π ⁰ π ⁰ invariant mass (M ₀₀) distribution from K ^± → π ^± π ⁰ π ⁰ decay shows a cusp-like anomaly at M ₀₀ = 2 m ₊, where m ₊ is the charged pion mass. An analysis to extract the ππ scattering lengths in the isospin I = 0 and I = 2 states, a ₀ and a ₂, respectively, has been recently reported. In the present work the Dalitz plot of this decay is fitted to a new empirical parameterization suitable for practical purposes, such as Monte Carlo simulations of K ^± → π ^± π ⁰ π ⁰ decays.
