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 ...

Researchers from the Department of Energy's SLAC National Accelerator Laboratory and the University of California, Los ...

Once a surprise to physicists, these particles are useful tools inside and outside the realm of particle physics.

This sample of niobium has been treated in a process that is typical for preparing particle accelerator components. Tests have revealed how adding oxygen to such components makes them more efficient.

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 ...
