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