Accurate Inverse-Compton Models Strongly Enhance Leptophilic Dark Matter Signals

Isabelle John, Tim Linden

The annihilation of TeV-scale leptophilic dark matter into electron-positron pairs (hereafter $e^{+}{e}^{-}$) will produce a sharp cutoff in the local cosmic-ray $e^{+}{e}^{-}$ spectrum at an…
