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…
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.…
Numerically evaluating the bispectrum in curved field-space - with PyTransport 2.0
John W. Ronayne, David J. Mulryne
We extend the transport framework for numerically evaluating the power spectrum and bispectrum in multi-field inflation to the case of a curved field-space metric. This method natu…
