Physicists from Swansea University have developed a groundbreaking method for producing and trapping antihydrogen, allowing for the record trapping of 15,000 atoms in under seven hours. This breakthrough could help answer the question of why there is such an imbalance between matter and antimatter.
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.
Researchers at Tokyo University of Science have discovered a method to generate molecular ions from an ionic crystal by bombarding it with positrons. This breakthrough could lead to new applications in materials science, cancer therapy, and quantum computing.
A new experiment at CERN has shown that gravity pulls antimatter downward, eliminating the possibility of antigravity. The gravitational acceleration of antimatter is close to that for normal matter on Earth, with a value within about 25% of normal gravity.
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.
Magnetic antiskyrmions are stabilized in magnetic crystals and exhibit unique properties. The Forschungszentrum Juelich team successfully demonstrated the existence of these objects through high-resolution electron microscopy and advanced simulations.
Daya Bay Reactor Neutrino Experiment has produced the most precise measurement yet of theta13, a key parameter for understanding how neutrinos change their 'flavor.' The result will help physicists explore mysteries surrounding matter and the universe.
Scientists from RIKEN have developed a new cooling method that enables more precise measurements of protons and antiprotons' magnetic moment. This breakthrough uses sympathetic cooling to reach temperatures close to absolute zero, significantly improving the precision of previous experiments.
Researchers aim to discover if neutrinos are their own antiparticle, solving the cosmic asymmetry between matter and antimatter. The NEXT-BOLD project will build a new detector capable of detecting barium ions, a key indicator of this discovery.
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...
An ultra-sensitive sensor has been developed to detect the nuclear decay of heavy neutrinos, which could explain the cosmic asymmetry between matter and antimatter. The researchers used a new fluorescent molecule to capture the barium ion produced in the process, providing a clear signal.
Researchers at the Large Hadron Collider investigate the properties of particles and their antiparticles to understand the universe's matter-antimatter asymmetry. The ALICE experiment confirms the CPT theorem with the most accurate measurements to date.
Researchers suggest the Higgs field's motion may have created a temporary imbalance between particles and antiparticles, resulting in a small excess of matter. This asymmetry is believed to be responsible for the formation of stars and planets, making up most of the universe.
Researchers analyzed neutron decay patterns, placing constraints on theories explaining the universe's matter-antimatter imbalance. While no clear answer emerged, improved detector sensitivity limited possible explanations, offering a fresh perspective for future investigations.
Researchers at University of Innsbruck simulate Dirac equation using calcium ion, demonstrating Zitterbewegung and antiparticle behavior. The experiment provides a proof-of-principle for simulating relativistic quantum systems.
