Optimized perturbation theory for bound states: toy model and realistic problem

High Energy Physics - Phenomenology 2009-10-28 v1

Abstract

Within quantum mechanics model we study the problem of resummation of an asymptotic perturbation series for bound state parameters via optimization of the perturbative expansion. A possible application of the method to the positronium lifetime calculation is also briefly considered.
