The quarks, antiquarks, and gluons of the standard model have a color charge, in addition to all the other properties like mass and electric charge that other particles and antiparticles possess. All ...

Building experimental evidence suggests that the electron, muon and tau may feel different forces. When the tau lepton was discovered in the 1970s, it didn’t resolve any outstanding mysteries—it ...

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 ...

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 ...

Can the discovery of the Higgs boson particle help with time travel?,” asked a young Vernon Area Public Library patron who attended the Science Explorers program. Quarks, leptons and bosons are ...

The Henryk Niewodniczanski Institute of Nuclear Physics Polish Academy of Sciences Electrons with 'colleagues' - other leptons - are one of many products of collisions observed in the LHCb experiment ...

The Standard Model of particles and interactions is remarkably successful for a theory everyone knows is missing big pieces. It accounts for the everyday stuff we know like protons, neutrons, ...
