Self-tuning and the derivation of the Fab Four
Christos Charmousis, Edmund J. Copeland, Antonio Padilla +1
We have recently proposed a special class of scalar tensor theories known as the Fab Four. These arose from attempts to analyse the cosmological constant problem within the context…
Dynamical simulations of electroweak baryogenesis with fermions
Paul M. Saffin, Anders Tranberg
We perform real-time numerical lattice simulations of a one-family version of the Standard Model. We model the quantum fermions using the ensemble method and treat the bosonic scal…
Reducing heterotic M-theory to five dimensional supergravity on a manifold with boundary
Ian G. Moss, John T. Omotani, Paul M. Saffin
This paper constructs the reduction of heterotic -theory in eleven dimensions to a supergravity model on a manifold with boundary in five dimensions using a Calabi-Yau three-fol…
Colliding branes and big crunches
John Omotani, Paul M. Saffin, Jorma Louko
We examine the global structure of colliding domain walls in AdS spacetime and come to the conclusion that singularities forming from such collisions are of the big-crunch type rat…
General second order scalar-tensor theory, self tuning, and the Fab Four
Christos Charmousis, Edmund J. Copeland, Antonio Padilla +1
Starting from the most general scalar-tensor theory with second order field equations in four dimensions, we establish the unique action that will allow for the existence of a cons…
Real-time Fermions for Baryogenesis Simulations
Paul M. Saffin, Anders Tranberg
We study how to numerically simulate quantum fermions out of thermal equilibrium, in the context of electroweak baryogenesis. We find that by combining the lattice implementation o…
