Current and Future $γ$-Ray Searches for Dark Matter Annihilation Beyond the Unitarity Limit
The astrophysical journal / 2 938(1)
For decades, searches for electroweak-scale dark matter (DM) have been performed without a definitive detection. This lack of success may hint that DM searches have focused on the wrong mass range. A proposed candidate beyond the canonical parameter space is ultraheavy DM (UHDM). In this work, we consider indirect UHDM annihilation searches for masses between 30 TeV and 30 PeV—extending well beyond the unitarity limit at ∼100 TeV—and discuss the basic requirements for DM models in this regime.doi:10.3204/pubdb-2022-04369 fatcat:nonomuf33vebbpqyecnrin3uka
