Dark matter scenarios with multiple spin-2 fields
N. L. Gonzalez Albornoz, Angnis Schmidt-May, Mikael von Strauss
We study ghost-free multimetric theories for tensor fields with a coupling to matter and maximal global symmetry group . Their mass spectra contain a mass…
Partially Massless Graviton on Beyond Einstein Spacetimes
Laura Bernard, Cedric Deffayet, Kurt Hinterbichler +1
We show that a partially massless graviton can propagate on a large set of spacetimes which are not Einstein spacetimes. Starting from a recently constructed theory for a massive g…
Heavy spin-2 Dark Matter
Eugeny Babichev, Luca Marzola, Martti Raidal +4
We provide further details on a recent proposal addressing the nature of the dark sectors in cosmology and demonstrate that all current observations related to Dark Matter can be e…
Gravitational Origin of Dark Matter
Eugeny Babichev, Luca Marzola, Martti Raidal +4
Observational evidence for the existence of Dark Matter is limited to its gravitational effects. The extensive program for dedicated searches has yielded null results so far, chall…
Linear spin-2 fields in most general backgrounds
Laura Bernard, Cedric Deffayet, Angnis Schmidt-May +1
We derive the full perturbative equations of motion for the most general background solutions in ghost-free bimetric theory in its metric formulation. Clever field redefinitions at…
Recent developments in bimetric theory
Angnis Schmidt-May, Mikael von Strauss
This review is dedicated to recent progress in the field of classical, interacting, massive spin-2 theories, with a focus on ghost-free bimetric theory. We will outline its history…
