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 Sp(4)c gauge theory with two Dirac fermions. https://www.hindigyanvishv.com/super-save-Smart-Tv-Led-32-Hd-Panasonic-32fs500b-2-Hdmi-2-Usb-Wi-fi-Conversor-Digital-super-buy/
