Is Stringy-Supersymmetry Quintessentially Challenged?
Abstract
Description
We discuss the problem of introducing background spacetimes of the de Sitter type (quintessential backgrounds) in the context of fundamental theories involving supersymmetry. The role of a model presented in 1984, showing that these backgrounds can occur as spontaneously broken phases of locally supersymmetric 4D, N-extended theories, is highlighted. The present twin challenges of the presumed presence of supersymmetry in particle physics and the emergence of experimental evidence for a positive cosmological constant from type-II supernovae data are noted for the continued investigation of superstring/M-theory. Finally we note how the 1984-model may have a role to play in future investigations.
