“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 ...

There’s a newfound mismatch between matter and antimatter. And that could bring ... But some particles disobey this symmetry, a phenomenon known as charge-parity, or CP, violation.

Physicists have, for the first time, seen a matter particle from the proton family behave in a fundamentally different way from its antimatter twin. The finding — which fits with behaviours ...

First observed in the 1960s among a class of particles called mesons, which are made up of a quark–antiquark pair, the violation of "charge-parity (CP)" symmetry has been the subject of intense ...

The purpose of this note is to direct attention to what may be a close analogue to the evolution of ‘local pockets’ of matter and antimatter in the Universe.
