摘要：

The NA48/2 experiment at the CERN SPS has collected a large sample of charged kaon decays. From the 2003 and most of 2004 statistics, the pi pi scattering lengths a(0)(0) and a(0)(2) have been extracted through the interpretation of an anomaly (cusp) in the pi(0)pi(0) effective mass distribution of the decay K-+/- -> pi(+/-)pi(0)pi(0). Using 2003 data, the form factors of K-e4 decays have been obtained, allowing the independent measurement of the same pi pi scattering parameters.
