The Derivation of Deser's Formula and Electromagnetic Corrections to the Pionium Life Time
Abstract
Description
We give the modern derivation of Deser's formula using analytic continuation of the scattering amplitude as a function of momentum. The electromagnetic corrections to the pionium lifetime are given as evaluated in a potential model.
