The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

Do kaons decay using a new kind of physics? Researchers are trying to explain their anomalous findings. Their larger experiment is an ongoing investigation of CP symmetry. The anomalies could be ...

The Belle II experiment has recently made precise measurements of the lifetime of subatomic particles called quarks and leptons (such as electrons and neutrinos). These particles are believed to be ...

Anomalous radio signals detected in Antarctica by the ANITA experiment were coming upward from Earth rather than down from the sky. Researchers used digital and mathematical simulations to test ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.
