AMS-02 experiment on ISS detects unexpected antihelium increase, possibly indicating WIMP decay or annihilation.
A recent study in the Journal of Cosmology and Astroparticle Physics highlights unexpected detections of antihelium particles by the AMS-02 experiment on the International Space Station. This increase may signal the presence of Weakly Interacting Massive Particles (WIMPs), a candidate for dark matter, suggesting they might be decaying or annihilating, creating both matter and antimatter. These findings could challenge existing astrophysical theories and imply new physics is needed.
