Titre |
Scrutinizing current predictions for cosmic-ray antiparticles |
|
Résumé |
The 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. |
