Strong constraints on dark photon and scalar dark matter decay from INTEGRAL and AMS-02 data

Author(s): Thong T. Q. Nguyen, Isabelle John, Tim Linden, and Tim M. P. TaitWe investigate the decay of bosonic dark matter with masses between 1 MeV and 2 TeV into Standard Model final states. We specifically focus on dark photons that kinetically mix with the Standard Model, as well as scalar dark matter models that have Yukawa couplings with the Standard Model. Using INT…[Phys. Rev.
