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.

Proton collisions at the LHC appear wildly chaotic, but new data reveal a surprising underlying order. The findings confirm that a basic rule of quantum mechanics holds true even in extreme particle ...

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 ...

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 ...
