Effective field theory reproducing the MOND phenomenology based on a non-Abelian Yang-Mills graviphoton

Luc Blanchet, Emeric Seraille

Motivated by the phenomenology of MOND, we propose a theory based on a fundamental non Abelian Yang-Mills gauge field with gravitational coupling constant (a "graviphoton") emergin…

Dipolar dark matter theory based on a non-Abelian Yang-Mills field

Luc Blanchet, Emeric Seraille

Most theories that attempt to reproduce the Modified Newtonian Dynamics (MOND) phenomenology for dark matter at galactic scales rely on ad hoc free functions, preventing them from…

Khronon-Tensor theory reproducing MOND and the cosmological model

Luc Blanchet, Constantinos Skordis

We propose an alternative scalar-tensor theory based on the Khronon scalar field labeling a family of space-like three-dimensional hypersurfaces. This theory leads to modified Newt…

Gravitational radiation reaction for compact binary systems at the fourth-and-a-half post-Newtonian order

Luc Blanchet, Guillaume Faye, David Trestini

We compute the gravitational radiation-reaction force on a compact binary source at the fourth-and-a-half post-Newtonian (4.5PN) order of general relativity, i.e., 2PN order beyond…

Relativistic Khronon Theory in agreement with Modified Newtonian Dynamics and Large-Scale Cosmology

Luc Blanchet, Constantinos Skordis

We propose an extension of General Relativity (GR) based on a space-time foliation by three-dimensional space-like hypersurfaces labeled by the Khronon scalar field . We show t…
