Results from NA48/2 on $\pi-\pi$ scattering lengths measurements in $K^{\pm} \rightarrow \pi^{+}\pi^{-}e^{\pm}\nu$ and $K^{\pm} \rightarrow \pi^{0}\pi^{0}\pi^{\pm}$ decays
Very large statistics of charged kaon decays have been accumulated in 2003-2004 by the NA48/2 experiment at the CERN SPS. The analyses of K ± → π 0π 0π ± (K3π) and K ± → π +π −e ±ν (Ke4) decays give complementary approaches to the study of low energy ππ scattering. From data samples of 60 millions K...
