Quark ,Leptons and Gauge bosons are a family of elementary particles.
Quarks: Quarks are the fundamental building blocks of nature. They combine to form larger particles, such as protons and neutrons. There are six different types of quarks: up, down, charm, strange, top, and bottom. Top quark is much heavier than the up quark. Some Quarks have a charge of +2/3 of an electron's charge (where e = 1.9 x 10-19 C) and some have a charge of -1/3 of an electron's charge. You may think this is strange because you were taught that you can't have a fraction of the charge on an electron. Your instinct is correct: because of this fractional charge, quarks can not exist independently; they must combine to form larger particles.
Leptons-Electrons ,muons and tauons are a few leptons.Leptons are the six particles including electrons , muons , tauons. Electron is a familiar particle .The muon and the tauons are the heavier, less well known cousins to the electron. The muon and tau are rarer than the electron, have the same negative charge that the electron has. Leptons are much lighter than the quarks, in fact the neutrinos are so light that there is debate whether they have mass at all!
Each lepton has a corresponding antiparticle – these antiparticles are known as antileptons.
Gauge Bosons:Particles that carry the fundamental forces of nature are Gauge bosons .They are elementary particles that cannot be subdivided.
The Standard Model of particle physics is a theory which describes the strong, weak, and electromagnetic fundamental forces which states that there are three kinds of gauge bosons: photons, W and Z bosons and guons
W and Z bosons mediate the weak force.
Photons are gauge bosons of the electromagnetic interaction.
Gluons carry the Strong interaction .
