GUT Scale Unification in Heterotic Strings
Carlo Angelantonj, Ioannis Florakis
We present a class of heterotic compactifications where it is possible to lower the string unification scale down to the GUT scale, while preserving the validity of the perturbativ…

One-loop Amplitudes as BPS state sums
Ioannis Florakis
We review a novel method for evaluating one-loop BPS-saturated amplitudes in string theory. Contrary to traditional techniques of unfolding the fundamental domain F against the Nar…

Orbifold Symmetry Reductions of Massive Boson-Fermion Degeneracy
Ioannis Florakis, Costas Kounnas
We investigate the existence of string vacua with Massive Spectrum Degeneracy Symmetry (MSDS) in Heterotic and Type II orbifold constructions. We present a classification of all po…
