Indirect detection of secluded supersymmetric dark matter

Weak-scale secluded sector dark matter can reproduce the observed relic density with thermal freeze-out within that sector. If nature is supersymmetric, three portals to visible - a gauge portal, Higgs and gaugino portal are present. We present gamma ray spectra relevant for indirect detection of annihilation in such setups. Since symmetries stabilize matter, $R$-parity unnecessary, we investigate impact violation on spectra. limits from Fermi Large Area Telescope observations dwarf galaxies projections Cherenkov Array galactic center.
