Within the framework of gauge mediated supersymmetry breaking, we consider an electroweak symmetry breaking pattern in which there is no conventional μ term. The pattern is made appealing through realizing it as low energy effective description of a supersymmetric Yang–Mills theory which is of confinement. Phenomenological implications are discussed.

A supersymmetric model with two copies of the Standard Model gauge groups is constructed in the gauge mediated supersymmetry breaking scenario. The supersymmetry breaking messengers are in a simple form. The Standard Model is obtained after first step gauge symmetry breaking. In the case of one copy of the gauge interactions being strong, a scenario of electroweak symmetry breaking is discussed, and the gauginos are generally predicted to be heavier than the sfermions.

The SU(4) color models represent possible alternatives to the standard model. These theories replace the color gauge group SU(3) c by SU(4) c . The SU(4) c symmetry is assumed to be broken which leads to the SM as the effective low energy theory. An interesting feature of these theories is that the SU(4) symmetry breaking scale can be very low, and may be approximately at the same scale as the electroweak symmetry breaking. These models imply the existence of exotic electrically charged ±1/2 fermions. We examine various SU(4) c models to explore the circumstances under which these models can have the exotic charged fermions in the interesting mass range m≳100 GeV .

Possible deviations from a low-energy theorem for the scattering of strongly interacting longitudinally polarized W and Z bosons are discussed within a particular scheme of electroweak symmetry breaking. The scheme (suggested earlier by other authors in a slightly different context) is based on spontaneous breakdown of an SU(4) symmetry to custodial SU(2) subgroup. The physical spectrum of such a model contains a set of relatively light pseudo-Goldstone bosons whose interactions with vector bosons modify the low-energy theorem proven for a "minimal" symmetry-breaking sector The Goldstone-boson manifold SU(4)/SU(2) is not a symmetric space. In this context it is observed that, on the other hand, there is a large class of models of electroweak symmetry breaking, involving groups G and H such that the G/H is a symmetric space and the corresponding rich multiplets of pseudo-Goldstone bosons do not influence the canonical low-energy theorem. For the scheme considered here, the relevant interactions are described in terms of an effective chiral Lagrangian and tree-level contributions of the pseudo-Goldstone boson exchanges to the vector boson scattering are computed explicitly. A comparison with the standard model is made.
