String Loop Threshold Corrections for N=1 Generalized Coxeter Orbifolds

Christos Kokorelis

We discuss the calculation of threshold corrections to gauge coupling constants for the, only, non-decomposable class of abelian (2, 2) symmetric N=1 four dimensional heterotic orb…

Gauge and Gravitational Couplings from Modular Orbits in Orbifold Compactifications

Christos Kokorelis

We discuss the appearance of modular functions at the one-loop gauge and gravitational couplings in (0,2) non-decomposable N=1 four dimensional orbifold compactifications of the he…
