Dark matter direct detection from new interactions in models with spin-two mediators

Blog Article

Abstract We consider models where a massive spin-two resonance acts as the mediator between Dark Matter (DM) and the SM particles through the energy-momentum tensor.We examine the effective theory for fermion, vector and scalar DM generated in these models and find novel types of read more DM-SM interaction never considered before.We identify the effective interactions between orange zinger tomato DM and the SM quarks when the mediator is integrated out, and match them to the gravitational form factors relevant for spin-independent DM-nucleon scattering.We also discuss the interplay between DM relic density conditions, direct detection bounds and collider searches for the spin-two mediator.
