Supersymmetric Composite Model with Dynamical Supersymmetry Breaking

Abstract

We present a supersymmetric composite model with dynamical supersymmetry breaking. The model is based on the gauge group SU(2)ₛ × SU(2)H × SU(3)c × SU(2)L × U(1)ᵧ. Supersymmetry is dynamically broken by the nonperturbative effect of the SU(2)ₛ “supercolor” interaction. The large top quark Yukawa coupling is naturally generated by the SU(2)H “hypercolor” interaction as recently proposed by Nelson and Strassler. The supersymmetry breaking is mediated to the standard model sector by a new mechanism. The electroweak symmetry breaking is caused by the radiative correction due to the large top quark Yukawa coupling with supersymmetry breaking. This is the “radiative breaking scenario,” which originates from the dynamics of the supercolor and hypercolor gauge interactions.
