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…
Gauged Galileons
Sebastian Garcia-Saenz, Jonghee Kang, Riccardo Penco
We discuss the gauging of non-linearly realized symmetries as a method to systematically construct spontaneously broken gauge theories. We focus in particular on galileon fields an…
Hyper non-Gaussianities in inflation with strongly non-geodesic motion
Jacopo Fumagalli, Sebastian Garcia-Saenz, Lucas Pinol +2
Several recent proposals to embed inflation into high-energy physics rely on inflationary dynamics characterized by a strongly non-geodesic motion in negatively curved field space.…
