Recent results from NA48/2 on pion scattering lengths in $K_{e4}$ decay and cusp in $K^{\pm} \rightarrow \pi^{\pm}\pi^{0}\pi^{0}$

The computation of pion scattering lengths $a^{0}_{0}$ and $a_{0}^{2}$ has been addressed in two independent analyses by the NA48/2 collaboration: the variation of the phase shift $\delta = \delta^{0}_{0} − \delta^{1}_{1}$ in $K^{\pm} \rightarrow \pi^{\pm}\pi^{\pm} e^{\pm}\nu$ $(Ke_{4})$ decay and t...
