Description
The determination of an antideuteron component in the cosmic-ray flux is one of the most interesting topics in the current search for exotic sources of antimatter, such as dark matter annihilation. Experiments like AMS-02 and GAPS were developed with, among others, the aim to search for a detectable antideuteron flux, over a wide energy range. In this task, it is also important to produce the best possible estimates of a secondary antideuteron background. Inelastic collisions undergone by primary cosmic particles with interstellar and atmospheric matter, as well as with the detector matter itself are considered here. For that purpose we use the widely used EPOS-LHC Monte Carlo generator, coupled with an event-by-event coalescence-model afterburner, to simulate antideuteron production in high energy proton-proton and proton-nucleus collisions.
