The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

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 ...

Almost anything is possible — at least for a subatomic particle. One of the many mystifying consequences of quantum mechanics — the rules that govern the behavior of tiny subatomic particles — is that ...

A new measurement finds the universe's teensiest particles weigh no more than one-millionth the mass of an electron. Reading time 2 minutes Physicists have placed a new limit on how big the elusive ...
