Vainshtein mechanism after GW170817
Marco Crisostomi, Kazuya Koyama
The almost simultaneous detection of gravitational waves and a short gamma-ray burst from a neutron star merger has put a tight constraint on the difference between the speed of gr…
Self-accelerating universe in scalar-tensor theories after GW170817
Marco Crisostomi, Kazuya Koyama
The recent simultaneous detection of gravitational waves and a gamma ray burst from a neutron star merger significantly shrank the space of viable scalar-tensor theories by demandi…
Beyond Lovelock gravity: Higher derivative metric theories
Marco Crisostomi, Karim Noui, Christos Charmousis +1
We consider theories describing the dynamics of a four-dimensional metric, whose Lagrangian is diffeomorphism invariant and depends at most on second derivatives of the metric. Imp…
Higher Derivative Field Theories: Degeneracy Conditions and Classes
Marco Crisostomi, Remko Klein, Diederik Roest
We provide a full analysis of ghost free higher derivative field theories with coupled degrees of freedom. Assuming the absence of gauge symmetries, we derive the degeneracy condit…
