Multiscale constraints on scalar-field couplings to matter: The geodetic and frame-dragging effects / Benisty, David (Cambridge U., DAMTP ; Cambridge U., KICC) ; Brax, Philippe (IPhT, Saclay ; CERN) ; Davis, Anne-Christine (Cambridge U., DAMTP ; Cambridge U., KICC)
The impact of light scalars coupled conformally and disformally to matter on the geodetic and frame-dragging (FD) precessions is calculated. For larger frequencies the disformal interaction becomes increasingly relevant. [...]

Casimir Tests of Scalar-Tensor Theories / Brax, Philippe (IPhT, Saclay ; CERN) ; Davis, Anne-Christine (Cambridge U., DAMTP) ; Elder, Benjamin (Hawaii U.)
We compute bounds and forecasts on screened modified gravity theories, specialising to the chameleon model in Casimir force experiments. In particular, we investigate the classical interaction between a plate and sphere subject to a screened interaction of the chameleon type. [...]

Stringent Pulsar Timing Bounds on Light Scalar Couplings to Matter / Benisty, David (Cambridge U., DAMTP ; Cambridge U., KICC) ; Brax, Philippe (IPhT, Saclay ; CERN) ; Davis, Anne-Christine (Cambridge U., DAMTP ; Cambridge U., KICC)
Pulsar Timing constraints on scalar-tensor theories with conformal and disformal couplings to matter are discussed. Reducing the dynamics to the motion in the centre of mass frame and using the mean anomaly parametrisation, we find the first post-Newtonian corrections induced by the conformal and disformal interactions in the form of a generalized quasi-Keplerian solution. [...]

The Dilaton and Modified Gravity / Brax, Philippe ; van de Bruck, Carsten ; Davis, Anne-Christine ; Shaw, Douglas J
We consider the dilaton in the strong string coupling limit and elaborate on the original idea of Damour and Polyakov whereby the dilaton coupling to matter has a minimum with a vanishing value at finite field-value. Combining this type of coupling with an exponential potential, the effective potential of the dilaton becomes matter density dependent. [...]

Modifying Gravity at Low Redshift / Brax, Philippe ; van de Bruck, Carsten ; Davis, Anne-Christine ; Shaw, Douglas
We consider the growth of cosmological perturbations in modified gravity models where a scalar field mediates a non-universal Yukawa force between different matter species. The growth of the density contrast is altered for scales below the Compton wave-length of the scalar field. [...]

Higgs production as a probe of dark energy interactions / Brax, Philippe ; Burrage, Clare ; Davis, Anne-Christine ; Seery, David ; Weltman, Amanda
We study Higgs production under the influence of a light, scalar dark energy field with chameleon-like couplings to matter. Our analysis is relevant for hadron colliders, such as the Large Hadron Collider, which are expected to manufacture Higgs particles through weak boson fusion, or associated production with a Z or W.

Microwave Background Constraints on Decaying Defects / Brandenberger, Robert H. (CERN ; Brown U.) ; Carter, Brandon (Meudon Observ.) ; Davis, Anne-Christine (Cambridge U., DAMTP)
Embedded defects are predicted in a host of particle physics theories, in particular in the standard electroweak theory. They can be stabilized by interactions with the cosmological plasma, but will decay once the plasma falls out of equilibrium, emitting a substantial fraction of non-thermal photons. [...]

Thermal stabilization of superconducting sigma strings and their drum vortons / Carter, Brandon (Meudon Observ.) ; Brandenberger, Robert H. (Brown U. ; CERN) ; Davis, Anne-Christine (Cambridge U., DAMTP)
We discuss various issues related to stabilized embedded strings in a thermal background. In particular, we demonstrate that such strings will generically become superconducting at moderately low temperatures, thus enhancing their stability. [...]

Examples of embedded defects / Lepora, Nathan F. (Cambridge U.) ; Davis, Anne-Christine (Cambridge U. ; CERN)
We present a series of examples designed to clarify the formalism of the companion paper `Embedded Vortices'. After summarising this formalism in a prescriptive sense, we run through several examples: firstly, deriving the embedded defect spectrum for Weinberg-Salam theory, then discussing several examples designed to illustrate facets of the formalism.
