Higgs vacuum (in)stability during inflation: the dangerous relevance of de Sitter departure and Planck-suppressed operators
Jacopo Fumagalli, Sébastien Renaux-Petel, John W. Ronayne
The measured Standard Model parameters lie in a range such that the Higgs potential, once extrapolated up to high scales, develops a minimum of negative energy density. This has im…
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…
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.…
On backreaction effects in geometrical destabilisation of inflation
Oskar Grocholski, Marcin Kalinowski, Maciej Kolanowski +3
We study the geometrical instability arising in multi-field models of inflation with negatively-curved field space. We analyse how the homogeneous background evolves in presence of…
