Virtual particles may not be real, but they help physicists track how forces move, and allow for incredibly precise ...

A clever mathematical tool known as virtual particles unlocks the strange and mysterious inner workings of subatomic particles. What happens to these ...

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 ...

Physicists are drawing closer to answering a long-standing mystery of the Universe: how long a neutron lives. Neutrons are electrically neutral particles that usually combine with protons to make up ...

A new study suggests that many theorized heavy particles, if they exist at all, do not have the properties needed to explain the predominance of matter over antimatter in the universe. If confirmed, ...

Chalk up a potential third win for hypothetical particles called axions. If the subatomic particles exist, they could solve two pressing puzzles of particle physics: the source of the dark matter that ...
