On Possibility of Higgs Mechanism Break Down Due to the Instantons

Abstract

Two-dimensional Abelian Higgs model is considered. It is shown that Higgs mechanism of the gauge bosons masses generating is broken in presence of instantons. It is supposed that discussion can be generalized into the standard model of electroweak interactions.
