Test of chiral perturbation theory with DIRAC at CERN / DIRAC Collaboration
The DIRAC experiment at CERN aims to form pi /sup +/ pi /sup -/ 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. [...]

Ratio of productions of $\pi^{+}\pi^{-}$ atoms to free $\pi^{+}\pi^{-}$ pairs with account of the strong interaction in final states / Afanasiev, L G (Dubna, JINR) ; Voskresenskaya, O O (Dubna, JINR)
The ratio of productions of pi+pi- atoms to free pi+pi- pairs is calculated with account of the strong interaction in final states. It is shown that this ratio is expressed via a squared ratio of the well-known Coulomb wave functions and thus can be calculated with a high accuracy..
