Counting String Theory Standard Models
Andrei Constantin, Yang-Hui He, Andre Lukas
We derive an approximate analytic relation between the number of consistent heterotic Calabi-Yau compactifications of string theory with the exact charged matter content of the sta…
Formulae for Line Bundle Cohomology on Calabi-Yau Threefolds
Andrei Constantin, Andre Lukas
We present closed form expressions for the ranks of all cohomology groups of holomorphic line bundles on several Calabi-Yau threefolds realised as complete intersections in product…
Calabi-Yau Manifolds and SU(3) Structure
Magdalena Larfors, Andre Lukas, Fabian Ruehle
We show that non-trivial SU(3) structures can be constructed on large classes of Calabi-Yau three-folds. Specifically, we focus on Calabi-Yau three-folds constructed as complete in…
NS5-Branes and Line Bundles in Heterotic/F-Theory Duality
Andreas P. Braun, Callum R. Brodie, Andre Lukas +1
We study F-theory duals of heterotic line bundle models on elliptically fibered Calabi-Yau threefolds. These models necessarily contain NS5-branes which are geometrised in the dual…
Matter Field Kahler Metric in Heterotic String Theory from Localisation
Stefan Blesneag, Evgeny I. Buchbinder, Andrei Constantin +2
We propose an analytic method to calculate the matter field Kähler metric in heterotic compactifications on smooth Calabi-Yau three-folds with Abelian internal gauge fields. The ma…
