SUMMARY:Fermion Creation by Cosmic Perturbations at 1-loop - Azadeh Malekn
 ejad (King's College London)

DESCRIPTION:Weyl spin 1/2 fermions\, when minimally coupled to Einstein's 
 gravity\, cannot be produced purely gravitationally in an expanding univer
 se at tree level. However\, this picture changes at the gravitational 1-lo
 op level in the presence of cosmic perturbations\, leading to a new and un
 avoidable mechanism for gravitational particle production. In this talk\, 
 I will explore the theory and phenomenological implications of this new ef
 fect.
