Numerical analysis of the pi+pi- atom lifetime in ChPT

Abstract

We apply Chiral Perturbation Theory at one loop to analyze the general formula for the pi+pi- atom lifetime derived recently in the framework of QCD. The corresponding analytic expression is investigated numerically, and compared with recent work in the literature.
