Abstract
The DIRAC experiment at CERN aims to form pi (+)pi (-) atomic states and to measure their lifetime with 10% accuracy. This will give a precision of 5% in the determination of pi pi S-wave scattering lengths, of the same level of Chiral Perturbation Theory calculations. In this way a crucial test on the theory validity would be performed.
