description

We investigate the perturbative regime of the Minimal Supersymmetric Con- formal Technicolor and show that it allows for a stable vacuum correctly breaking the electroweak symmetry. We nd that the particle spectrum is richer than the MSSM one since it features several new particles stemming out from the new N = 4 sector of the theory. The parameter space of the new theory is reduced imposing naturalness of the cou- plings and soft supersymmetry breaking masses, perturbativity of the model at the EW scale as well as phenomenological constraints. By studying the RGEs at two loops we nd that the Yukawa couplings of the heavy fermionic states
