The building blocks of matter that have been experimentally verified are the quarks and leptons described by the Standard Model. Since the discovery of the electron in 1897, physicists have identified ...

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 ...

For the first time, quarks and gluons were used to describe properties of atomic nuclei, which until now had been explained by the existence of protons and neutrons. The temporary pair of correlated ...

Nuclear puzzle: In the nucleus, neutrons can be stable, but free neutrons decay after a short period. Exactly how short is in dispute because experiments on neutrons stored in bottles and neutrons in ...
