Pion scattering lengths from NA48
The anomaly (cusp) in the mass spectrum of two neutral pions from the three-pion decays of charged kaon has been observed in the NA48/2 experiment. Using the recently developed interpretation of this effect in terms of Chiral Perturbative Theory, the pion scattering parameters are measured. The prel...
