Abstract

Elementary particle physics is outlined plainly in the three-part tutorial. In this second part, gauge particles are explained such as photon, which intermediate the electromagnetic force. The essence of the gauge particles lies in their gauge symmetry hence the difference in the gauge symmetries implies varying nature of the interaction mediated by each gauge particle. The gauge particles that mediate the weak interaction and the strong interaction and their importance in elementary particle physics are explained. An important concept called “breaking of symmetry” is introduced and the significance of Higgs boson is narrated.
