BPS Spectra and Non--Perturbative Couplings in N=2,4 Supersymmetric String Theories
Gabriel Lopes Cardoso, Gottfried Curio, Dieter Lust +2
We study the BPS spectrum in heterotic string compactifications, with some emphasis on intermediate BPS states. These intermediate states, which can become short i…
Perturbative and Non-Perturbative Results for Heterotic Strings
G. Lopes Cardoso, D. Lust, T. Mohaupt
In this paper we summarize our recent work about perturbative and non-perturbative effects in four-dimensional heterotic strings with space-time supersymmetry.
On-Mass-Shell Gaugino Condensation in Z_{N} Orbifold Compactifications
Ingo Gaida, Dieter Luest
We discuss non-perturbative aspects of string effective field theories with N=1 supersymmetry in four dimensions. By the use of a scalar potential, which is on-shell invariant unde…
Non-perturbative monodromies in N=2 heterotic string vacua
Gabriel Lopes Cardoso, Dieter Lüst, Thomas Mohaupt
We address non-perturbative effects and duality symmetries in heterotic string theories in four dimensions. Specifically, we consider how each of the four lines of enhanced g…
Threshold Corrections and Symmetry Enhancement in String Compactifications
Gabriel Lopes Cardoso, Dieter Lüst, Thomas Mohaupt
We present the computation of threshold functions for Abelian orbifold compactifications. Specifically, starting from the massive, moduli-dependent string spectrum after compactifi…
