Diffeomorphism-invariant averaging in quantum gravity and cosmology
Anthony W. H. Preston
This thesis concerns research undertaken in two related topics concerning high-energy gravitational physics. The first is the construction of a manifestly diffeomorphism-invariant…
Cosmological backreaction in higher-derivative gravity expansions
Anthony W. H. Preston
We calculate a general effective stress-energy tensor induced by cosmological inhomogeneity in effective theories of gravity where the action is Taylor-expandable in the Riemann te…
Manifestly diffeomorphism invariant classical Exact Renormalization Group
Tim R. Morris, Anthony W. H. Preston
We construct a manifestly diffeomorphism invariant Wilsonian (Exact) Renormalization Group for classical gravity, and begin the construction for quantum gravity. We demonstrate tha…
Cosmological back-reaction in modified gravity and its implications for dark energy
Anthony W. H. Preston, Tim R. Morris
We study the effective stress-energy tensor induced by cosmological inhomogeneity in and equivalent scalar-tensor theories, motivated both by models of early universe…
LHC and Tevatron bounds on the dark matter direct detection cross-section for vector mediators
Mads T. Frandsen, Felix Kahlhoefer, Anthony Preston +2
We study the interactions of a new spin-1 mediator that connects the Standard Model to dark matter. We constrain its decay channels using monojet and monophoton searches, as well a…
