Robust cosmic-ray constraints on p -wave annihilating MeV dark matter

We recently proposed a method to constrain $s$-wave annihilating MeV dark matter from a combination of the Voyager 1 and the AMS-02 data on cosmic-ray electrons and positrons. Voyager 1 actually provides an unprecedented probe of dark matter annihilation to cosmic rays down to $\ensuremath{\sim}10\t... View More
