| Abstract: |
Apart from its gravitational interactions, dark matter (DM) has remained so far elusive in laboratory searches. We revisit the case of DM interacting just gravitationally with the Standard Model (SM) particles in an extra-dimensional Randall-Sundrum scenario. After discussing several possibilities with two branes, we consider the case of three branes: the Planck brane, a TeV-PeV IR brane, where the Standard Model is located, and a GeV-TeV deep IR (DIR) one, where the DM lies. In this setup, the relic abundance of DM arises from the freeze-out mechanism, thanks to DM annihilations into radions and gravitons. Focusing on a scalar singlet DM candidate, we compute and apply current and future constraints from direct, indirect and collider-based searches. Our findings demonstrate the viability of this scenario and highlight its potential testability in upcoming experiments. |
