Recasting and Forecasting Dark Matter Limits Without Raw Data: A Generalized Algorithm for Gamma-Ray Telescopes

Giacomo D'Amico, Michele Doro, Michela De Caria

We present a novel method for both forecasting and recasting upper limits (ULs) on dark matter (DM) annihilation cross sections, ${⟨\sigma v⟩}^{UL}$, or decay lifetime $τ^{LL}…
