Universal moduli-dependent thresholds in Z$_{2}$ x Z$_{2}$ orbifolds
In the context of a recently proposed method for computing exactly string loop corrections regularized in the infra-red, we determine and calculate the universal moduli-dependent part of the threshold corrections to the gauge couplings for the symmetric Z_2\times Z_2 orbifold model. We show that the...
