New measurement of the $K^{\pm} \to \pi^+\pi^-e^{\pm}\nu(K_{e4} )$ decay branching ratio and hadronic form factors

A sample of more than one million $K^{\pm} \rightarrow \pi^{+} \pi^{-} e^{\pm} \nu$ ($K_{e4}$) decay candidates with less than one percent background contamination has been collected by the NA48/2 experiment at the CERN SPS in 2003--2004, allowing a detailed study of the decay properties. The bran...
