Positrons in Cosmic Rays from Dark Matter Annihilations for Uplifted Higgs Regions in MSSM

Understand

We point out that there are regions in the MSSM parameter space which successfully provide a dark matter (DM) annihilation explanation for observed positron excess (e.g.

• PAMELA), while still remaining in agreement with all other data sets.
• Such regions (e.g.
• the uplifted Higgs region) can realize an enhanced neutralino DM annihilation dominantly into leptons via a Breit-Wigner resonance through the CP-odd Higgs channel.
