Resumen

Antinuclei found in cosmic rays could provide a smoking gun signal for dark matter as this signal is virtually background free. The study of ³He cosmic rays requires the knowledge of their production, propagation in the galaxy and annihilation cross-section. While the former two have been already estimated with data-driven methods, there were no experimental data available for the ³He inelastic cross section. We measured for the first time the inelastic cross section of ³He using the ALICE detector itself as a target. To study the effect of ³He annihilation in the galaxy and estimate the transparency of the galaxy, the ³He source functions and annihilation cross sections were implemented in GALPROP.
