Abstract: The breakdown of gauge symmetry within Grand Unified Theories (GUTs) can result in supersymmetric (SUSY) extensions of the Standard Model (SM) at low energies, which allows the electroweak scale to be almost stabilized. The gauge coupling unification, Higgs sector, and restrictions on the sparticle spectrum are considered in the framework of several SUSY extensions of the SM. Possible manifestations of these SUSY models and existing experimental limits are also discussed.

Keywords: Grand Unified Theories and models, extensions of the Standard Model, supersymmetry, dark matter, non-standard Higgs bosons, supersymmetric partners of known particles, leptoquarks, exotic particles.
