Hitchin Functionals and Nonspontaneous Supersymmetry Breaking

Abstract

A new mechanism of supersymmetry breaking involving a dynamical parameter is introduced. It is independent of particle phenomenology and gauge groups. An explicit realization of this mechanism takes place in Type II superstring compactifications which admit eight supercharges (also known as generalized SU(3) structures). The resulting Kahler potentials are expressed in terms of Hitchin functionals.
