The @ALICEexperiment reports the first measurement of the absorption of anti-3He nuclei in matter and the impact on its propagation in the galaxy.
The measurement was performed by using the ALICE detector and quantifying the inelastic interactions of the anti-3He nuclei produced in proton-proton (pp) and lead-lead (Pb-Pb) collisions.
These measurements are used in order to obtain the transparency of our galaxy to the passage of anti-3He nuclei, for different possible source, including WIMP dark matter annihilations. The results show that about half of the produced anti-3He can reach the detection points in the #solarsystem and support such probes as suited for the indirect search of #darkmatter.
