Classification and Properties of Hyperconifold Singularities and Transitions
Rhys Davies
This paper is a detailed study of a class of isolated Gorenstein threefold singularities, called hyperconifolds, that are finite quotients of the conifold. First, it is shown that…
Quantum black holes in Type-IIA String Theory
Pablo Bueno, Rhys Davies, C. S. Shahbazi
We study black hole solutions of Type-IIA Calabi-Yau compactifications in the presence of perturbative quantum corrections. We define a class of black holes that only exist in the…
Dirac gauginos and unification in F-theory
Rhys Davies
Supersymmetric models in which the gauginos acquire Dirac masses, rather than Majorana masses, offer an appealing alternative to the minimal supersymmetric standard model, especial…
The MSSM Spectrum from (0,2)-Deformations of the Heterotic Standard Embedding
Volker Braun, Philip Candelas, Rhys Davies +1
We construct supersymmetric compactifications of E_8 \times E_8 heterotic string theory which realise exactly the massless spectrum of the Minimal Supersymmetric Standard Model (MS…
Small neutrino masses due to R-symmetry breaking for a small cosmological constant
Rhys Davies, Matthew McCullough
We describe a class of supersymmetric models in which neutrinos are kept light by an R-symmetry. In supergravity, R-symmetry must be broken to allow for a small cosmological consta…
The Expanding Zoo of Calabi-Yau Threefolds
Rhys Davies
This is a short review of recent constructions of new Calabi-Yau threefolds with small Hodge numbers and/or non-trivial fundamental group, which are of particular interest for mode…
