On velocity-dependent dark matter annihilations in dwarf satellites

“…In conclusion, our study has provided the first quantitative and data-based attempt in literature to bracket the uncertainty in the prediction of prompt photon emission from DM annihilation stemming from the modeling of the phase-space distribution function in the classical dwarf satellites of the Galaxy. We wish to remark that the results reported in figure 7 of this paper may trigger the interest of current experimental facilities such as Fermi-LAT [73], HAWC [74], H.E.S.S [75], MAGIC [76] and VERITAS [77], and may be of further relevance for next-gen ones, such as CTA [78], e-ASTROGAM [79] and AMEGO [80]. On more general grounds, we believe that the approach outlined in this work may serve as a future baseline for a systematic investigation on the relevance of DM phase-space distribution modelling in the vast realm of indirect searches.…”

Dark Matter in scalar Sp($$ \mathcal{N} $$) gauge dynamics

“…We calculate the relevant cross sections for the direct and indirect detections and compare them with the current experimental limits as well as the future prospects, and we find that the Sp DM model is testable on the future indirect detection experiment like CTA [6]. We also investigate the phenomenology of the scalon and of light glueballs and their connection with Higgs physics.…”

Secluded dark matter in light of the Cherenkov Telescope Array (CTA)

“…Instead of follow other analysis including that made by the collaboration [82][83][84] which gives an optimistic scenario, we choose this methodology described above in order to be conservative, previous analysis do not consider GDE and/or do not take into account systematic uncertainties (related, for example, to the acceptance of the experiment in a Field of View (FoV)), here we are considering both possibilities, therefore, we are following a conservative approach as given by [45].…”
