On the Coupling of Generalized Proca Fields to Degenerate Scalar-Tensor Theories
Sebastian Garcia-Saenz
We prove that vector fields described by the generalized Proca class of theories do not admit a consistent coupling to a gravitational sector defined by a scalar-tensor theory of t…
Destabilization of black holes and stars by generalized Proca fields
Sebastian Garcia-Saenz, Aaron Held, Jun Zhang
We demonstrate that black holes and stars in general relativity can be destabilized by perturbations of non-minimally coupled vector fields. Focusing on static and spherically symm…
Supersymmetric Partially Massless Fields and Non-Unitary Superconformal Representations
Noah Bittermann, Sebastian Garcia-Saenz, Kurt Hinterbichler +1
We find and classify the simplest SUSY multiplets on AdS which contain partially massless fields. We do this by studying representations of the , …
Degeneracy, matter coupling, and disformal transformations in scalar-tensor theories
Cédric Deffayet, Sebastian Garcia-Saenz
Degenerate scalar-tensor theories of gravity extend general relativity by a single degree of freedom, despite their equations of motion being higher than second order. In some case…
Revisiting non-Gaussianity in multifield inflation with curved field space
Sebastian Garcia-Saenz, Lucas Pinol, Sébastien Renaux-Petel
Recent studies of inflation with multiple scalar fields have highlighted the importance of non-canonical kinetic terms in novel types of inflationary solutions. This motivates a th…
A theory for multiple partially massless spin-2 fields
Nicolas Boulanger, Cédric Deffayet, Sebastian Garcia-Saenz +1
We revisit the problem of building consistent interactions for a multiplet of partially massless spin-2 fields in (anti-)de Sitter space. After rederiving and strengthening the exi…
