A Monte Carlo Calculation of the Pionium Break-up Probability with Different Sets of Pionium Target Cross Sections
Chiral Perturbation Theory predicts the lifetime of pionium, a hydrogen-like $pi^+ pi^-$ atom, to better than 3% precision. The goal of the DIRAC experiment at CERN is to obtain and check this value experimentally by measuring the break-up probability of pionium in a target. In order to accurately m...
