After a decade and a half of research motivated by the accelerating universe, theory and
experiment have reached a certain level of maturity. The development of theoretical models …

We review recent progress in massive gravity. We start by showing how different theories of
massive gravity emerge from a higher-dimensional theory of general relativity, leading to the …

Massive gravity has seen a resurgence of interest due to recent progress which has
overcome its traditional problems, yielding an avenue for addressing important open …

A bstract Single top-quark production in association with a Z boson, where the Z boson
decays to a pair of charged leptons, is measured in the trilepton channel. The proton-proton …

A bstract Theories of massive gravity inevitably include an auxiliary reference metric.
Generically, they also contain an inconsistency known as the Boulware-Deser ghost …

A bstract In massive gravity and in bimetric theories of gravity, two constraints are needed to
eliminate the two phase-space degrees of freedom of the Boulware-Deser ghost. For …

A bstract The consistency of the EFT of two interacting spin-2 fields is checked by applying
forward limit positivity bounds on the scattering amplitudes to exclude the region of …

A bstract We perform a helicity decomposition in the full Lagrangian of the class of Massive
Gravity theories previously proven to be free of the sixth (ghost) degree of freedom via a …

We consider a procedure for directly constructing general tree-level four-particle scattering
amplitudes of massive spinning particles that are consistent with the usual requirements of …

A bstract We place model-independent constraints on theories of massive spin-2 particles by
considering the positivity of the phase shift in eikonal scattering. The phase shift is an …
