Supersymmetric Partially Massless Fields and Non-Unitary Superconformal Representations
Sebastian Garcia-Saenz, Kurt Hinterbichler, Rachel A. Rosen
We find and classify the SUSY multiplets on AdS which contain partially massless fields. We do this by studying the non-unitary representations of the superc…
Black Hole Pulsar
Janna Levin, Daniel J. D'Orazio, Sebastian Garcia-Saenz
In anticipation of a LIGO detection of a black hole/neutron star merger, we expand on the intriguing possibility of an electromagnetic counterpart. Black hole/Neutron star mergers…
Consistent deformations of free massive field theories in the Stueckelberg formulation
Nicolas Boulanger, Cédric Deffayet, Sebastian Garcia-Saenz +1
Cohomological techniques within the Batalin-Vilkovisky (BV) extension of the Becchi-Rouet-Stora-Tyutin (BRST) formalism have proved invaluable for classifying consistent deformatio…
Flattened non-Gaussianities from the effective field theory of inflation with imaginary speed of sound
Sebastian Garcia-Saenz, Sébastien Renaux-Petel
Inflationary perturbations in multi-field theories can exhibit a transient tachyonic instability as a consequence of their non-trivial motion in the internal field space. When an e…
Primordial fluctuations and non-Gaussianities in sidetracked inflation
Sebastian Garcia-Saenz, Sébastien Renaux-Petel, John Ronayne
Heavy scalar fields can undergo an instability during inflation as a result of their kinetic couplings with the inflaton. This is known as the geometrical destabilization of inflat…
