Light inflaton model in a metastable Universe
Fedor Bezrukov, Abigail Keats
We minimally extend the SM with a Z symmetric potential containing a single scalar field, serving as our inflaton with a quartic self-coupling. In the model we have symmetry br…

Heavy Light Inflaton and Dark Matter Production
Fedor Bezrukov, Abigail Keats
We study the minimal extension of the SM by a scalar with quartic interaction serving as an inflaton. For the model where scale symmetry is broken only in the inflaton sector, the…
