Post-Newtonian phenomenology of a massless dilaton
A. Hees, O. Minazzoli
In this paper, we present extensively the observational consequences of massless dilaton theories at the post-Newtonian level. We extend previous work by considering a general mode…
On dilatons with intrinsic decouplings
Olivier Minazzoli, Aurélien Hees
In this paper, we show that there exists a class of dilaton models with non-trivial scalar-Ricci and scalar-matter couplings that strongly reduces observational deviations from gen…
Merging matter and geometry in the same Lagrangian
Hendrik Ludwig, Olivier Minazzoli, Salvatore Capozziello
We show that a Lagrangian density proportional to reduces to a pressuron theory of gravity that is indistinguishable from General Relativity in the dust limit.…
Basics of the pressuron
Olivier Minazzoli, Aurélien Hees
The pressuron is a specific case of a dilaton-like field that leads to a decoupling of the scalar-field in the field equation for pressureless fluids. Hence, the pressuron recovers…
Some cosmological consequences of a breaking of the Einstein equivalence principle
A. Hees, O. Minazzoli, J. Larena
In this communication, we consider a wide class of extensions to General Relativity that break explicitly the Einstein Equivalence Principle by introducing a multiplicative couplin…
