Theory seminar: Antideuterons from Dark Matter and Hadronization Dependence

Lars Andreas Dal, UiO

The nature of Dark Matter is one of the large open questions in physics today. Observations indicate that Dark Matter likely consists of an unknown species of particles, which allows for the possibility of indirectly detecting Dark Matter by searching for the decay/annihilation products from these particles in cosmic rays.

With its very low expected astrophysical background, the antideuteron channel is particularly well suited for such searches. I will here discuss the challenges in correctly calculating the expected cosmic ray antideuteron flux, with focus on the uncertainty from hadronization models employed in Monte Carlo event generators.
