Production of cosmic-ray antinuclei in the Galaxy and background for dark matter searches

Nicola Tomassetti, Alberto Oliva

Antimatter nuclei in cosmic rays (CR) represent a promising discovery channel for the indirect search of dark matter. We present astrophysical background calculations of CR antideu…

Secondary antinuclei from supernova remnants and background for dark matter searches

Nicola Tomassetti, Alberto Oliva

We compute the spectra of cosmic-ray (CR) nuclei and antinuclei under a scenario where hadronic interaction processes inside supernova remnants (SNRs) can produce a diffusively-sho…

Production of antimatter nuclei in Galactic cosmic rays

Alberto Oliva, Nicola Tomassetti, Jie Feng

Antimatter nuclei in cosmic rays (CRs) are a promising tool for the indirect detection of dark-matter annihilation signatures. However, the search of new-physics signals in CRs rel…

Evidence for a Time Lag in Solar Modulation of Galactic Cosmic Rays

Nicola Tomassetti, Miguel Orcinha, Fernando Barao +1

The solar modulation effect of cosmic rays in the heliosphere is an energy-, time-, and particle-dependent phenomenon which arises from a combination of basic particle transport pr…
