Cosmic-ray antideuteron searches
Philip von Doetinchem (University of
Hawai’i at Manoa)
Recent
years have seen increased theoretical and experimental efforts towards
the first-ever detection of cosmic-ray antideuterons, in particular as
an indirect signature of dark matter annihilation or decay. In contrast
to indirect dark matter searches using positrons, antiprotons, or
gamma-rays, which suffer from relatively high and uncertain
astrophysical backgrounds, searches with antideuterons benefit from very
suppressed conventional backgrounds, offering a potential breakthrough
in unexplored phase space for dark matter. The presentation will review
dark matter theories that can be probed with antideuterons, the
challenges for the interpretations of antideuteron signals, and the
experimental efforts toward cosmic antideuteron detection.
