We consider the case of small coupling constant α, but fixed Zα and ultraviolet cut-off Λ. We prove that after renormalizing the mass the binding energy has, to leading order in α, a finite limit as Λ goes to infinity; i.e., the cut-off can be removed. The expression for the ground state energy shift thus obtained agrees with Bethe's formula for small values of Zα, but shows a different behavior for bigger values.","lang":"eng"}],"publisher":"International Press","publist_id":"4574","article_processing_charge":"No","issue":"5","language":[{"iso":"eng"}],"citation":{"ista":"Hainzl C, Seiringer R. 2002.
