Cosmic Ray nuclei in the energy range 100 MeV/nuc - 100 GeV/nuc provide crucial information about the physical properties of the Galaxy. They can also be used to answer questions related to astroparticle physics. This paper reviews the results obtained in this direction, with a strong bias towards the work done by the authors at {\sc lapth}, {\sc isn} and {\sc iap}. The propagation of these nuclei is studied quantitatively in the framework of a semi-analytical two-zone diffusion model taking into account the effect of galactic wind, diffuse reacceleration and energy losses. The parameters of this model are severely constrained by an analysis of the observed B/C ratio. These constraints are then used to study other species such as radioactive species and light antinuclei. Finally, we focus on the astroparticle subject and we study the flux of antiprotons and antideuterons that might be due to neutralino annihilations or primordial black hole evaporation. The question of the spatial origin of all these species is also addressed.

  1. Constraints on Primordial Black Holes from Galactic Diffuse Synchrotron Emissions

    hep-ph 2026-01 conditional novelty 5.0 of 10

    Galactic synchrotron emissions above 20 MHz can set tighter upper limits on the abundance of primordial black holes with masses above 10^16 grams than previous cosmic-ray electron data.

  2. Refined anti-proton and anti-deuteron fluxes from weak-scale Dark Matter

    astro-ph.HE 2026-06 accept novelty 4.0 of 10

    Updated tabulated interstellar fluxes of antiprotons and antideuterons from weak-scale DM are provided using new propagation schemes and inelastic cross-sections, showing greater robustness than prior calculations.

  3. Unveiling the Mechanisms of Electron Energy Spectrum Evolution

    hep-ph 2024-12 conditional novelty 4.0 of 10

    The paper attributes the electron spectrum's low-energy cooling tail, mid-energy diffusion plateau, and TeV cooling cutoff to two diffusion timescales in a spatially dependent propagation model.
