Heterotic parafermionic superstring

Heterotic parafermionic superstring.

Superstrings have been postulated based on parafermionic partition functions which permit spacetime supersymmetry by generalized Jacobi identities. A comprehensive search finds new such identities. Quadrilateral anomaly cancellation gives constraints on allowed chiral fermions. Bosonic left-movers and Z4 parafermionic right-movers combine in a new heterotic superstring, more constrained than th...

Duality Symmetries in N = 2 Heterotic Superstring

We review the derivation and the basic properties of the perturbative prepotential in N=2 compactifications of the heterotic superstring. We discuss the structure of the perturbative monodromy group and the embedding of rigidly supersymmetric monodromies associated with enhanced gauge groups, at both perturbative and non-perturbative level.

Topological Amplitudes in Heterotic Superstring Theory ⋆

We show that certain heterotic string amplitudes are given in terms of correlators of the twisted topological (2,0) SCFT, corresponding to the internal sector of the N = 1 spacetime supersymmetric background. The genus g topological partition function F g corresponds to a term in the effective action of the form W 2g , where W is the gauge or gravitational superfield. We study also recursion re...

Quadratic Divergences in Effective Supergravity from the Heterotic Superstring

Results from studies of effective Lagrangians for gaugino condensation are summarized and re-examined with an eye to previously neglected one-loop quadratically divergent corrections. Talk presented at the Nathfest, Northeastern University, Boston, MA, August 14–15, 2004, to be published in the proceedings of PASCOS04. This work was supported in part by the Director, Office of Energy Research, ...
