N = 2 noscale supergravity
Abstract
N = 2 extended supergravity is discussed and an assessment is made of the problems encountered in applying it to the construction of phenomenological models of particle physics. A specific class of socalled noscale models is discussed, in which the two supersymmetries are spontaneously broken in flat spacetime, with naturally vanishing cosmological constant and the scale of supersymmetry breaking undetermined at the classical level. Supergravityinduced supersymmetry breaking generates effective mass terms for spin {1}/{2} components of the vector gauge multiplets and spin0 components of the scalar matter multiplets. For finite globally supersymmetric models, this supersymmetry breaking preserves the finiteness. Possible connections of N = 2 noscale supergravity with superstrings and finite range antigravity are mentioned.
