Accidental SUSY: Enhanced Bulk Supersymmetry from Brane Back-reaction
C. P. Burgess, L. van Nierop, S. Parameswaran +2
We compute how bulk loops renormalize both bulk and brane effective interactions for codimension-two branes in 6D gauged chiral supergravity, as functions of the brane tension and…
Inflating in a Trough: Single-Field Effective Theory from Multiple-Field Curved Valleys
C. P. Burgess, M. W. Horbatsch, Subodh P. Patil
We examine the motion of light fields near the bottom of a potential valley in a multi-dimensional field space. In the case of two fields we identify three general scales, all of w…
Modulated Reheating and Large Non-Gaussianity in String Cosmology
M. Cicoli, G. Tasinato, I. Zavala +2
A generic feature of the known string inflationary models is that the same physics that makes the inflaton lighter than the Hubble scale during inflation often also makes other sca…
Non-standard primordial fluctuations and nongaussianity in string inflation
C. P. Burgess, M. Cicoli, M. Gomez-Reino +3
Inflationary scenarios in string theory often involve a large number of light scalar fields, whose presence can enrich the post-inflationary evolution of primordial fluctuations ge…
The Fate of Unstable Gauge Flux Compactifications
C. P. Burgess, S. L. Parameswaran, I. Zavala
Fluxes are widely used to stabilise extra dimensions, but if they arise within a non-abelian gauge sector they are often unstable. We seek the fate of this instability, focussing o…
On Bouncing Brane-Worlds, S-branes and Branonium Cosmology
C. P. Burgess, F. Quevedo, R. Rabadan +2
We present several higher-dimensional spacetimes for which observers living on 3-branes experience an induced metric which bounces. The classes of examples include boundary branes…
