Threshold Corrections in Heterotic String Theory from Conformal Perturbation Theory
Dilan Nur Demirtaş, Christoph A. Keller, Manki Kim
We use conformal perturbation theory to compute one-loop threshold corrections to the Kähler potential of the heterotic string. For this we consider the theory compactified at the…

On string loops in Calabi-Yau orientifolds in large volume
Manki Kim
We explain and illustrate how to compute string-loop amplitudes in Calabi-Yau orientifold compactification in the large volume limit with the help of the patch-by-patch description…
