  The present lectures contain an introduction to possible new physics beyond
the Standard Model. Having in mind first of all accelerator experiments of the
nearest future we concentrate on supersymmetry, a new symmetry that relates
bosons and fermions, as the first target of experimental search. Since
supersymmetry is widely covered in the literature, we mostly consider novel
developments and applications to hadron colliders. We describe then the
so-called extra dimensional models in less detail and discuss their possible
manifestations.
