SUMMARY:DM indirect searches with cosmic-ray antiparticles
DESCRIPTION:Speakers: Pedro de la Torre Luque (Stockholm University) \nThe creation of antiparticles in the Galaxy has been discussed as a potential signal of exotic production mechanisms such as primordial black hole evaporation or dark matter decay/annihilation\, in addition to the more conventional production from cosmic-ray (CR) interactions. Recent CR detectors have provided very accurate measurements on the spectra of antiprotons and positrons that we use to search for evidence of new physics. In addition\, the exciting first measurements of the flux of anti-nuclei can be achievable in a few years.In this talk\, I discuss the uncertainties related to the modelling of these antiparticles and show state-of-art predictions of their spectra. We will also talk about recent dark matter constraints from antiprotons and positrons and discuss the expected fluxes of anti-deuteron and anti-helium from global analyses of different CR observables in view of the first tentative detection of anti-nuclei events by the AMS-02 collaboration. Finally\, if time allows it\, I will discuss an ongoing study where we use CR data to place constrains of DM candidates beyond WIMPs (e.g. ALPs\, sterile neutrinos\, …) coupling with electrons. \nhttps://indico.in2p3.fr/event/29312/
