The Standard Model of particle physics predicts an asymmetry between matter and antimatter known as charge–parity (CP) ...

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 ...

Particles and antiparticles have opposite charges, and they annihilate if they interact, turning into pure energy. In the Big Bang, an equal amount of matter and antimatter formed, but some process ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...
