Moduli Axions, Stabilizing Moduli and the Large Field Swampland Conjecture in Heterotic M-Theory

Cédric Deffayet, Burt A. Ovrut, Paul J. Steinhardt

We compute the potential energy for the dilaton, complex structure and Kahler moduli and search of realistic vacua of heterotic M-theory compactified on Calabi-Yau threefolds. We p…
