چکیده
We evaluate theoretical uncertainties to the method of Pais and Treiman to measure the ππ phase shifts in Ke4 decays. We find that they are very small, below 1%.

Isospin breaking in Kl4 decays
Data on Ke4 decays allow one to extract experimental information on the elastic ππ scattering amplitude near threshold, and to confront the outcome of the analysis with predictions made in the framework of QCD. These predictions concern an isospin symmetric world, while experiments are carried out in the real world, where isospin breaking effects – generated by electromagnetic interactions and ...
متن کاملTwo Measurements of Ππ Scattering Lengths a and a from Studies Of
The NA48 experiment at the CERN SPS has used 0 L K and 0 S K kaons for the precise measurement of the direct CP violation parameter Re(ε'/ε). In 2002 it was re-designed as NA48/2 to search for CP violation in K → 3π decays. This configuration has also allowed studying several rare decay processes of charged kaons to test chiral perturbation theory. With data samples of ~10 K±→π±π-eν decays, pre...
متن کاملTheoretical progress on cusp effect and Kl4 decays
The cusp effect in K → 3π and data on Ke4 decays allow one to extract experimental information on the elastic ππ scattering amplitude near threshold, and to confront the outcome of the analyses with predictions made in the framework of QCD. In my talk I pointed out that these predictions concern an isospin symmetric world, while experiments are carried out in the real world, where isospin break...
متن کاملWigner-cusp in Kaon Decays and Determination of Ππ Scattering Lengths
In the last few years it has become possible to study low energy ππ scattering in kaon decays to three pions, thanks to the high statistics measurement of K → πππ decays performed by the NA48/2 experiment at the CERN SPS. At the ππ threshold, the ππ mass spectrum exhibits a Wigner-cusp, from which the S-wave ππ scattering lengths are extracted with high precision. This measurement is complement...
متن کاملReanalysis of pion pion phase shifts from K → ππ decays
We re-investigate the impact of isospin violation for extracting the s-wave ππ scattering phase shift difference δ 0 (M K) − δ 2 (M K) from K → ππ decays. Compared to our previous analysis in 2003, more precise experimental data and improved knowledge of low-energy constants are used. In addition, we employ a more robust data-driven method to obtain the phase shift difference δ 0
