A Heterotic QCD Axion
Evgeny I. Buchbinder, Andrei Constantin, Andre Lukas
We show that a KSVZ axion with a decay constant in the phenomenologically allowed range can be obtained in certain heterotic string models. These models have an enh…
Type IIB flux vacua from G-theory II
Philip Candelas, Andrei Constantin, Cesar Damian +2
We find analytic solutions of type IIB supergravity on geometries that locally take the form with a generalised complex manifold. The…
Type IIB flux vacua from G-theory I
Philip Candelas, Andrei Constantin, Cesar Damian +2
We construct non-perturbatively exact four-dimensional Minkowski vacua of type IIB string theory with non-trivial fluxes. These solutions are found by gluing together, consistently…
Hypercharge Flux in Heterotic Compactifications
Lara B. Anderson, Andrei Constantin, Seung-Joo Lee +1
We study heterotic Calabi-Yau models with hypercharge flux breaking, where the visible E8 gauge group is directly broken to the standard model group by a non-flat gauge bundle, rat…
Non-generic Couplings in Supersymmetric Standard Models
Evgeny I. Buchbinder, Andrei Constantin, Andre Lukas
We study two phases of a heterotic standard model, obtained from a Calabi-Yau compactification of the E8xE8 heterotic string, in the context of the associated four-dimensional effe…
A Heterotic Standard Model with B-L Symmetry and a Stable Proton
Evgeny I. Buchbinder, Andrei Constantin, Andre Lukas
We consider heterotic Calabi-Yau compactifications with S(U(4)xU(1)) background gauge fields. These models lead to gauge groups with an additional U(1) factor which, under certain…
