Title (deu)
Non-perturbative Resolution of Strong Coupling Singularities in 4d N=1
Speaker / Lecturer
Max Wiesner
Harvard U, Cambridge
Description (deu)
This talk is part of the thematic programme on "The Landscape vs. the Swampland". We study strong coupling regimes in compactifications of the heterotic string to 4d with N=1 supersymmetry. We show that perturbative threshold corrections to the heterotic string lead to strong coupling singularities that do not have a counterpart in the analogue N=2 compactifications of Type IIA on Calabi-Yau threefolds. These strong coupling singularities naively cut off the moduli space leading to a boundary of the moduli space at finite distance. However, non-perturbative effects are expected to partially resolve these singularities allowing to continue the moduli space past them. Using duality to M-theory we are able to compute these non-perturbative corrections and show how these resolve strong coupling singularities. This talk is based on work to appear with Mirjam Cvetic.
