from Topological Amplitudes in String Theory
Ioannis Florakis, Ahmad Zein Assi
In this paper, we explicitly construct string theory backgrounds that realise the so-called gauge theory. We prove the consistency of our models by calculating…
Generalised universality of gauge thresholds in heterotic vacua with and without supersymmetry
Carlo Angelantonj, Ioannis Florakis, Mirian Tsulaia
We study one-loop quantum corrections to gauge couplings in heterotic vacua with spontaneous supersymmetry breaking. Although in non-supersymmetric constructions these corrections…
Probing the Moduli Dependence of Refined Topological Amplitudes
Ignatios Antoniadis, Ioannis Florakis, Stefan Hohenegger +2
With the aim of providing a worldsheet description of the refined topological string, we continue the study of a particular class of higher derivative couplings in the ty…
Universality of radiative corrections to gauge couplings for strings with spontaneously broken supersymmetry
Ioannis Florakis
I review recent work on computing radiative corrections to non-abelian gauge couplings in four-dimensional heterotic vacua with spontaneously broken supersymmetry. The prototype mo…
Threshold corrections, generalised prepotentials and Eichler integrals
Carlo Angelantonj, Ioannis Florakis, Boris Pioline
We continue our study of one-loop integrals associated to BPS-saturated amplitudes in heterotic vacua. We compute their large-volume behaviour, and express them as…
