Title: Can massive gravitons be an ideal FIMP Dark Matter candidate?

Speaker: Giacomo Cacciapaglia (IP2I Lyon)

Abstract: Massive gravitons, not to be confused with the gravity mediators, are spin-2 states that carry mass and have gravitational-strength interactions to other particles. They are considered to be too weakly coupled to be sizeably produced in the Universe.  We discovered a chiral enhancement in some scattering processes that allow massive gravitons to saturate the Dark Matter relic density via freeze-in. This scenario can be realised in a warped 5-dimensional model with two branes.
