Precise tests of low energy QCD from $K_{e4}$ decay properties

We report results from the analysis of the $K^{\pm} \rightarrow \pi^{+} \pi^{-} e^{\pm} \nu$ (Ke4) decay by the NA48/2 collaboration at the CERN SPS, based on the total statistics of 1.13 million decays collected in 2003-2004. The hadronic form factors in the S- and P-wave and their variation with e...
