Standard Model

Part of the Springer Theses book series (Springer Theses)


The Standard Model of Particle Physics is a gauge theory of the group \(U_{Y_\mathrm{{w}}}(1)\,\times \,SU_{L}(2)\,\times \,SU_{c}(3) \). The gauge group is a direct product of three groups. Therefore, we will first briefly analyse them individually and assign to each sub-group a different type of interaction. Afterwards, we will organise the tree-level interaction pattern of all elementary particles by combining the sub-groups. Gauge invariance under the full gauge group requires all elementary fields to be massless. Finally, we will explain how the observed masses are generated by the phenomenon of spontaneous symmetry breaking and the Higgs mechanism.
