One and two loop phenomenology in heterotic string theory
We examine the phenomenological properties of certain heterotic string theories through the computation of one and two-loop amplitudes. Initially, we consider the fate of shift-symmetries in effective string models is considered beyond tree-level. Such symmetries have been proposed in the past as a...
