Glimmers of antimatter to explain the "dark" part of the universe

A recent study suggests that the observation of antihelium nuclei in cosmic rays may be consistent with the existence of WIMP particles, which could make up dark matter. The detection of two distinct isotopes, antihelium-3 and -4, is particularly intriguing as heavier nuclei are unlikely to be produced through natural processes.

Down goes antimatter! Gravity's effect on matter's elusive twin is revealed

Researchers confirmed that antimatter falls under the influence of gravity, ruling out gravitational repulsion as a cause for its absence in the universe. The study used an antihydrogen experiment to observe individual atoms taking a downward path, providing a definitive answer to long-standing questions about antimatter's behavior.

Researchers develop novel approach to modeling yet-unconfirmed rare nuclear process

Physicists at Michigan State University's Facility for Rare Isotope Beams have developed a new method to model neutrinoless double-beta decay, a yet-unconfirmed rare nuclear process with significant implications for particle physics and cosmology. The novel approach, known as the In-Medium Generator-Coordinate Method, enables controlle...
