A determination of the S-wave pion-pion scattering lengths from the measurement of the lifetime of pionium

The aim of the DIRAC Experiment at CERN is to provide an accurate determination of the S-wave pi pi scattering lengths from the measurement of the lifetime of pi /sup +/ pi /sup -/ atoms. The precision of the measurement will submit low-energy predictions from Chiral Perturbation Theory to a stringe...

description The aim of the DIRAC Experiment at CERN is to provide an accurate determination of the S-wave pi pi scattering lengths from the measurement of the lifetime of pi /sup +/ pi /sup -/ atoms. The precision of the measurement will submit low-energy predictions from Chiral Perturbation Theory to a stringent test. We illustrate the performance of the experimental apparatus and present some preliminary results from the analysis of a 1999 data sample.
