Order α^2 corrections to the decay rate of orthopositronium

Abstract

Order α^2 corrections to the decay rate of orthopositronium are calculated in the framework of nonrelativistic QED. The resulting contribution is found to be in significant disagreement with one set of experimental measurements though another experiment is in agreement with theory.
