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 ...

Observations of extremely rare subatomic particle actions have allowed scientists to put one of the most stringent limits yet on the reigning theory of particle physics. Physicists at the world's ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

When it comes to talent, versatility and the power to change the world, which atomic particle is the champ? Read what our four contenders have to say—then you decide. Physics fans, are you ready to ...

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 ...

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 ...

A pair of physicists announced the discovery of a subatomic event so powerful that the researchers wondered if it was too dangerous to make public. The explosive event? The duo showed that two tiny ...

Wolfgang Pauli, the Austrian physicist who predicted the neutrino’s existence, also won a Nobel, but not for the neutrino (he did a lot of other very important stuff). He might have won for the ...
