The Weak Interactions in the Confining Phase

Abstract

In this talk I will report on work done in collaboration with L.F. Abbott. The basic idea¹⁾ is to describe the weak interactions as arising from the structure of composite left-handed quarks and leptons. The right-handed quarks and leptons are point like at the scale of the weak interactions G ^−½_F ≃ 250 GeV. Our model can produce the same effective four Fermi interaction Lagrangian as the standard model. However for Q² bigger than zero the predictions of our model differ from those of the standard model.
