Instantons and Hilbert Functions
Evgeny I. Buchbinder, Andre Lukas, Burt A. Ovrut +1
We study superpotentials from worldsheet instantons in heterotic Calabi-Yau compactifications for vector bundles constructed from line bundle sums, monads and extensions. Within a…
Heterotic Instantons for Monad and Extension Bundles
Evgeny I. Buchbinder, Andre Lukas, Burt A. Ovrut +1
We consider non-perturbative superpotentials from world-sheet instantons wrapped on holomorphic genus zero curves in heterotic string theory. These superpotential contributions fea…
Machine learning Calabi-Yau metrics
Anthony Ashmore, Yang-Hui He, Burt Ovrut
We apply machine learning to the problem of finding numerical Calabi-Yau metrics. Building on Donaldson's algorithm for calculating balanced metrics on Kähler manifolds, we combine…
-parity Violating Decays of Bino Neutralino LSPs at the LHC
Sebastian Dumitru, Christian Herwig, Burt A. Ovrut
The -parity violating decays of Bino neutralino LSPs are analyzed within the context of the MSSM "heterotic standard model". These LSPs correspond to statistically determi…
