Heterotic Flux Vacua with a Small Superpotential

Evgeny I. Buchbinder, Andrei Constantin, Lucas T. Y. Leung +2

We study heterotic Calabi--Yau compactifications with NSNS three-form flux in view of moduli stabilisation and investigate whether the value of the flux superpotential eval…

Computation of Quark Masses from String Theory

Andrei Constantin, Kit Fraser-Taliente, Thomas R. Harvey +2

We present a numerical computation, based on neural network techniques, of the physical Yukawa couplings in a heterotic string theory compactification on a smooth Calabi-Yau threef…

Stable Vacua with Realistic Phenomenology and Cosmology in Heterotic M-theory Satisfying Swampland Conjectures

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

We recently described a protocol for computing the potential energy in heterotic M-theory for the dilaton, complex structure and Kähler moduli. This included the leading order non-…

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…

Numerical spectra of the Laplacian for line bundles on Calabi-Yau hypersurfaces

Anthony Ashmore, Yang-Hui He, Elli Heyes +1

We give the first numerical calculation of the spectrum of the Laplacian acting on bundle-valued forms on a Calabi-Yau three-fold. Specifically, we show how to compute the approxim…

FIMP Dark Matter in Heterotic M-Theory

Sebastian Dumitru, Burt A. Ovrut

Within the context of supersymmetric heterotic -theory, we present a "freeze-in" mechanism for producing dark matter via a "moduli portal" between the observable and hidde…
