Worldsheet Instantons and Torsion Curves
Volker Braun, Maximilian Kreuzer, Burt A. Ovrut +1
We study aspects of worldsheet instantons relevant to a heterotic standard model. The non-simply connected Calabi-Yau threefold used admits Z_3 x Z_3 Wilson lines, and a more detai…
Non-Gaussianities in New Ekpyrotic Cosmology
Evgeny I. Buchbinder, Justin Khoury, Burt A. Ovrut
New Ekpyrotic Cosmology is an alternative scenario of the early universe which relies on a phase of slow contraction before the big bang. We calculate the 3-point and 4-point corre…
Flux, Gaugino Condensation and Anti-Branes in Heterotic M-theory
James Gray, André Lukas, Burt Ovrut
We present the potential energy due to flux and gaugino condensation in heterotic M-theory compactifications with anti-branes in the vacuum. For reasons which we explain in detail,…
