Gravitational waves from fermion production during axion inflation
Peter Adshead, Lauren Pearce, Marco Peloso +2
We present analytic results for the gravitational wave power spectrum induced in models where the inflaton is coupled to a fermionic pseudocurrent. We show that although such a cou…
Phenomenology of fermion production during axion inflation
Peter Adshead, Lauren Pearce, Marco Peloso +2
We study the production of fermions through a derivative coupling with a pseudoscalar inflaton and the effects of the produced fermions on the scalar primordial perturbations. We p…
The phenomenology of trapped inflation
Lauren Pearce, Marco Peloso, Lorenzo Sorbo
Trapped inflation is a mechanism in which particle production from the moving inflaton is the main source of friction in the inflaton equation of motion. The produced fields source…
