Matter and antimatter should have completely wiped each other out eons ago, leaving the Universe a very empty place.

At one-one-thousandth of a second after the Big Bang, the great annihilation event should have wiped out all matter, leaving a universe of only radiation. Why still don't know why ...

Charge-parity violation is thought to explain why there’s more matter than antimatter in the universe. Scientists just spotted it in a new place.

Physicists have made a landmark discovery, uncovering the first clear evidence that matter particles, known as baryons, ...

That poses a problem for physicists: if matter and antimatter both were created equally in the Big Bang and behaved in the same way, as most physical laws suppose, then it’s difficult to explain ...

"We needed a machine like the LHC capable of producing a large enough number of beauty baryons and their antimatter counterparts, and we needed an experiment at that machine capable of pinpointing ...

The LHCb experiment at CERN has uncovered a fundamental asymmetry in the behavior of baryons. During the Moriond Conference in Italy, the LHCb collaboration at CERN announced that a new ...
