Dynamical compactification as a mechanism of spontaneous supersymmetry breaking
Abstract
Supersymmetry breaking and compactification of extra spacetime dimensions may have a common dynamical origin if our Universe is spontaneously generated in the form of a fourdimensional topological or nontopological defect in higherdimensional spacetime. Within such an approach the conventional particles are zeromodes trapped in the core of the defect. In many cases solutions of this type spontaneously break all supersymmetries of the original theory, so that the lowenergy observer from ``our'' Universe inside the core would not detect supersymmetry. Since the extra dimensions are not compact but, rather, inaccessible to lowenergy observers, the usual infinite tower of the KaluzaKlein excitations does not exist. Production of superpartners at the energy scale of SUSY restoration will be accompanied by fourmomentum nonconservation. (Depending on the nature of the solution at hand, the nonconservation may either happen above some threshold energy or be continuous). In either case, the door to extra dimensions may be not very far from the energies accessible at present colliders.
