Description
Abstract: The stable hadronic bound states in a hidden new non-Abelian gauge sector provide interesting candidates for strongly-interacting Dark Matter (DM). A particular example are theories in which DM is made up of dark pions which set the DM relic abundance through self-annihilation. One of the simplest realizations is a $Sp(4)$ gauge symmetry with two Dirac fermions. We will discuss its mesonic multiplets for degenerate and non-degenerate fermions and present lattice results for the pseudoscalar and vector channels.
