Article: Limits to gauge coupling in the dark sector set by the non-observation of instanton-induced decay of Super-Heavy Dark Matter in the Pierre Auger Observatory data

Upper limits at 95\% C.L. on the effective coupling constant of a hidden gauge interaction as a function of the mass of a dark matter particle X decaying into quark/anti-quark…

Article: Predicted diffuse flux of ultra-high energy photons in the galactic plane; its implications for the search for super-heavy dark matter

Upper limits on diffuse photon fluxes for several energy thresholds, and expected fluxes from UHECRs interactions with the gas distribution in the Galaxy (grey dashed and blue dashed-dotted lines), as…
