Productive interactions: Heavy particles, gravitational waves, and non-Gaussianity
I discuss the phenomenology of models of inflation with periodic particle production. Particle production occurs as the mass of heavy particles goes through non-adiabatic modulations as the inflaton field rolls. I show that this process can lead to the significant emission of scalar and gravitational waves during inflation, with distinct observational signatures. ...
