Description

Due to its low astrophysical background, the antideuteron channel is a highly promising channel for indirect detection of dark matter. Being an antinucleus, the antideuteron flux has additional uncertainties from the nucleus formation model that are not relevant for other indirect detection channels. The antideuteron formation model depends on very small momentum differences between antinucleons, making it highly sensitive to two-particle correlations arising from the hadronization models employed by Monte Carlo event generators. I will here discuss the influence of hadronization on antideuteron formation, and the uncertainty on the antideuteron flux this leads to. I will further discuss the prospects of reducing this uncertainty by tuning Monte Carlo generators specifically for antideuteron production.
