摘要：

In the last few years it has become possible to study low energy pi pi scattering with high precision in kaon decays, thanks to the high statistics measurements of K-+/- -> pi(+/-)pi(0)pi(0) (K-3 pi) and K-+/- -> pi(+)pi(-)e(+/-)nu (K-e4) decays performed by the NA48/2 experiment at the CERN SPS. In K-+/- -> pi(+/-)pi(0)pi(0), at the pi(+)pi(-) threshold, the pi(0)pi(0) mass spectrum exhibits a Wigner-cusp, from which the scattering lengths a(0) and a(2) are extracted. From the study of K-e4 decays a similar precision, but quite independent measurement of a(0) and a(2) can be obtained. The combination of both measurements provides one of the most stringent tests of Chiral Perturbation Theory.
