Inhomogeneous Hubble diagram from vector K-mouflage
Jose Beltran Jimenez, Dario Bettoni, Philippe Brax
In this Letter we construct the Hubble diagram for a Universe where dark matter is universally charged under a dark non-linear electromagnetic force which features a screening mech…
Generalized Proca and its Constraint Algebra
Jose Beltrán Jiménez, Claudia de Rham, Lavinia Heisenberg
We reconsider the construction of general derivative self-interactions for a massive Proca field. The constructed Lagrangian is such that the vector field propagates at most three…
The canonical frame of purified gravity
Jose Beltrán Jiménez, Lavinia Heisenberg, Tomi S. Koivisto
In the recently introduced gauge theory of translations, dubbed Coincident General Relativity, gravity is described with neither torsion nor curvature in the spacetime affine geome…
Stability of Horndeski vector-tensor interactions
Jose Beltrán Jiménez, Ruth Durrer, Lavinia Heisenberg +1
We study the Horndeski vector-tensor theory that leads to second order equations of motion and contains a non-minimally coupled abelian gauge vector field. This theory is remarkabl…
