Indirect Detection of Secluded Supersymmetric Dark Matter

Understand

Weak-scale secluded sector dark matter can reproduce the observed dark matter relic density with thermal freeze-out within that sector.

• If nature is supersymmetric, three portals to the visible sector - a gauge portal, a Higgs portal, and a gaugino portal - are present.
• We present gamma ray spectra relevant for indirect detection of dark matter annihilation in such setups.
• Since symmetries in the secluded sector can stabilize dark matter, $R$-parity is unnecessary, and we investigate the impact of $R$-parity violation on annihilation spectra.
