Abstract

An unbroken discrete symmetry, analogous to Gparity in QCD, exists in standard model extensions with vectorlike coupling of electroweak SU(2) to "hidden sector" fermions that are confined by a strong gauge force. For an arbitrary irreducible SU(2) representation of the hidden sector fermions, the lightest hidden sector states form an isotriplet of "pions" with calculable mass splittings and couplings to standard model fields. The parity can be extended to fermions in real representations of color SU(3), and can provide dark matter candidates with distinct collider signatures.
