Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
Interactions of multiple spin-2 fields beyond pairwise couplings
S. F. Hassan, Angnis Schmidt-May
Thus far, all known ghost-free interactions of multiple spin-2 fields have involved at most pairwise couplings of the fields, which are direct generalizations of bimetric interacti…
Analysis of constraints and their algebra in bimetric theory
S. F. Hassan, Anders Lundkvist
We perform a canonical analysis of the bimetric theory in the metric formulation, computing the constraints and their algebra explicitly. In particular, we compute a secondary cons…
Gauge and global symmetries of the candidate partially massless bimetric gravity
Luis Apolo, S. F. Hassan, Anders Lundkvist
In this paper we investigate a particular ghost-free bimetric theory that exhibits the partially massless (PM) symmetry at quadratic order. At this order the global SO(1,4) symmetr…
Non-linear partially massless symmetry in an SO(1,5) continuation of conformal gravity
Luis Apolo, S. F. Hassan
We construct a non-linear theory of interacting spin-2 fields that is invariant under the partially massless (PM) symmetry to all orders. This theory is based on the SO(1,5) group,…
Extended Weyl Invariance in a Bimetric Model and Partial Masslessness
S. F. Hassan, Angnis Schmidt-May, Mikael von Strauss
We revisit a particular ghost-free bimetric model which is related to both partial masslessness (PM) and conformal gravity. Linearly, the model propagates six instead of seven degr…
