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…
Structures in multiple spin-2 interactions
Oliver Baldacchino, Angnis Schmidt-May
We study generalisations of ghost-free bimetric theory which involve more than two spin-2 fields. The consistent interactions can enter in the form of two different couplings and i…
Nonlinear interactions for massive spin-2 fields
Angnis Schmidt-May
We give a basic introduction to ghost-free nonlinear theories involving massive spin-2 fields, focussing on bimetric theory. After motivating the construction of such models from f…
