Physics Letters B, 2011•ElsevierThe DIRAC experiment at CERN has achieved a sizeable production of π+ π− atoms and
has significantly improved the precision on its lifetime determination. From a sample of 21
227 atomic pairs, a 4% measurement of the S-wave ππ scattering length difference
[Formula: see text] has been attained, providing an important test of Chiral Perturbation
Theory.
