Abstract

Since the Higgs boson of the standard electroweak model has not been detected despite many experimental attempts, nonstandard electroweak models not including the Higgs boson may be worthy of consideration; one of them is proposed here. This new model of electroweak interactions is based on the Yang-Mills theory completed by a nontrivial condition at infinity for the Yang-Mills potentials corresponding to the zero-field intensities. It is shown that within the framework of this model the three vector potentials of the Yang-Mills theory allow one to describe both the Maxwell electromagnetic interactions and the Fermi weak interactions and to obtain the known value of the Z0 boson mass.
