Cosmology/Fundamental Theory: Phenomenology of Fermion Production During Axion Inflation 

While the production of bosons during inflation has received substantial attention, the production of fermions has often been neglected. Fermions can be produced via a derivative coupling during axion inflation; in this talk, I will present recent calculations illustrating phenomenologically interesting consequences. In particular, the CMB power spectrum fluctuations can be dominated by the sourced contribution while satisfying non-Gaussianity constraints, in contrast to bosonic production. Time permitting, I will also discuss recent results on the gravitational wave signal in this model.
