One loop amplitude for Heterotic string on T 2

Abstract : We revisit the results of one loop string amplitude calculations for the Heterotic string theory compactified on a torus with or without Wilson lines. We give the complete elliptic genus and the harmonic part of the CP-even amplitude for the gauge groups SO(32), E 8 × E 8 , SO(16) × SO(16) and SO(8) 4 .
