Journal ArticleDOI
The World Sheet Supergravity of the Heterotic String
Mark Evans,Burt A. Ovrut +1 more
TL;DR: Using the superfield formalism, this article derived the two-dimensional (p, 0) supergravity associated with the heterotic string, where ρ is a positive integer.
Journal ArticleDOI
A heterotic standard model
TL;DR: In this article, the existence of simple, realistic N = 1 supersymmetric vacua that are compatible with low energy particle physics was shown, in the context of the E8 × E8 heterotic superstring compactified on a smooth Calabi-Yau threefold with an SU(4) gauge instanton.
Journal ArticleDOI
Machine Learning Calabi─Yau Metrics
TL;DR: It is demonstrated that it is possible to find highly accurate numerical metrics much more quickly than by using Donaldson's algorithm alone, with the new machine‐learning algorithm decreasing the time required by between one and two orders of magnitude.
Journal ArticleDOI
Spontaneous R-parity breaking, stop LSP decays and the neutrino mass hierarchy
TL;DR: In this paper, the R-parity violating decays of a stop LSP into a bottom quark and charged leptons were analyzed using a wide scan over the parameter space.
Journal ArticleDOI
Effective Action of the N = 2 Maxwell Multiplet in Harmonic Superspace
Ioseph L. Buchbinder,Evgeny I. Buchbinder,E. A. Ivanov,Sergei M. Kuzenko,Burt A. Ovrut,Burt A. Ovrut +5 more
TL;DR: In this paper, a general method for constructing the off-shell effective action of an N=2 abelian gauge superfield coupled to matter hypermultiplets is presented, in the N = 2, D = 4 harmonic superspace formalism, where the only non-trivial radiative corrections to appear are non-holomorphic.
