Modified Yang-Mills Theory and Electroweak Interactions

Since the Higgs boson of the standard electroweak model has not been detecteddespite many experimental attempts, nonstandard electroweak models notincluding the Higgs boson may be worthy of consideration; one of them isproposed here. This new model of electroweak interactions is based on theYang-Mills theory completed by a nontrivial condition at infinity for theYang-Mills potentials corresponding to the zero-field intensities. It is shown thatwithin the framework of this model the three vector potentials of the Yang-Millstheory allow one to describe both the Maxwell electromagnetic interactions andthe Fermi weak interactions and to obtain the known value of the Z ⁰ boson mass.
