What charged cosmic rays tell us on dark matter
Autor: Pierre Salati
Publikováno v: SciPost Physics Proceedings, Iss 12, p 067 (2023)
Dark matter particles could be the major component of the haloes of galaxies. Their mutual annihilations or decays would produce an indirect signature under the form of high-energy cosmic-rays. The focus of this presentation is on antimatter species,

AMS-02 antiprotons and dark matter: Trimmed hints and robust bounds
Autor: Francesca Calore, Marco Cirelli, Laurent Derome, Yoann Genolini, David Maurin, Pierre Salati, Pasquale D. Serpico
Publikováno v: SciPost Physics, Vol 12, Iss 5, p 163 (2022)
Based on 4 yr AMS-02 antiproton data, we present bounds on the dark matter (DM) annihilation cross section vs. mass for some representative final state channels. We use recent cosmic-ray propagation models, a realistic treatment of experimental an

Observer l’Univers lointain permet de remonter à ses origines. Mais un mur que la lumière ne peut percer nous empêche d’accéder directement à la prime enfance du cosmos. Nous le franchirons cependant pour étudier dans ce chapitre le fluide

The precise measurement of cosmic-ray antinuclei serves as an important means for identifying the nature of dark matter and other new astrophysical phenomena, and could be used with other cosmic-ray species to understand cosmic-ray production and pro

Primordial black holes may have been produced in the early stages of the thermal history of the Universe after cosmic inflation. If so, dark matter in the form of elementary particles can be subsequently accreted around these objects, in particular w
