Predicting the properties of subatomic particles before their experimental discovery has been a big challenge for physicists. Predicting the properties of subatomic particles before their experimental ...

GENEVA — The physics lab that’s home to the world’s largest atom smasher announced on Tuesday the observation of three new “exotic particles” that could provide clues about the force that binds ...

Electrons are extremely round, and some physicists are not pleased about it. A new experiment captured the most detailed view of electrons to date, using lasers to reveal evidence of particles ...

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 ...
