Prospects on searches for baryonic Dark Matter produced in $${\varvec{b}}$$-hadron decays at LHCb

A model that can simultaneously explain Dark Matter relic density and the apparent matter anti-matter imbalance of the universe has been recently proposed. The model requires b -hadron branching fractions to Dark Matter at the per mille level. The b -hadrons decay to a dark sector baryon, , which has a mass in the region . In this paper, we discuss the sensitivity of the LHCb experiment to search for this dark baryon, covering different types of...
