  • Abstract
    We apply Chiral perturbation theory at one loop to analyze the general formula for the π+π− atom lifetime derived recently in the framework of QCD [A. Gall et al., Phys. Lett. B 462 (1999) 335]. The corresponding analytic expression is investigated numerically, and compared with recent work in the literature.
