Superexponential Cutoff as a Probe of Annihilating Dark Matter

Résumé

We investigate the possibility of fitting the putative spectrum of gamma rays from annihilating dark matter at the galactic center by a superexponential template. By generating and analyzing mock data for several ongoing and future experiments (HESS, CTA, and DMA), we find that the preference for a superexponential template (over an exponential) is especially strong for dark matter annihilating to τ+τ- and μ+μ- relative to other annihilation channels.
