Dangerous Angular KK/Glueball Relics in String Theory Cosmology
J. F. Dufaux, L. Kofman, M. Peloso
The presence of Kaluza-Klein particles in the universe is a potential manifestation of string theory cosmology. In general, they can be present in the high temperature bath of the…
Cosmological perturbations from braneworld inflation with a Gauss-Bonnet term
J. -F. Dufaux, J. Lidsey, R. Maartens +1
Braneworld inflation is a phenomenology related to string theory that describes high-energy modifications to general relativistic inflation. The observable universe is a braneworld…
Gauss-Bonnet gravity renders negative tension braneworlds unstable
Christos Charmousis, Jean-Francois Dufaux
We show that the Gauss-Bonnet correction to Einstein gravity induces a gravitational tachyon mode, namely an unstable spin 2 fluctuation, in the Randall-Sundrum I model. We demonst…
Scalar brane backgrounds in higher order curvature gravity
Christos Charmousis, Stephen C. Davis, Jean-Francois Dufaux
We investigate maximally symmetric brane world solutions with a scalar field. Five-dimensional bulk gravity is described by a general lagrangian which yields field equations contai…
