Module overview
Relativistic wave equations with their predictions of anti-particles and fermion spin will be explored. The fundamental role of gauge symmetries in current theories of force will lead to the study of the standard model of particle physics, including the spontaneous electroweak symmetry breaking via the Higgs mechanism.
Finally theories of particle physics beyond the standard model will be briefly investigated concentrating on their motivations and testable consequences.

Assessment
Assessment strategy
Non compulsory problem sheets are available on the website, including model answers, though they are not used for formal (summative) assessment purposes.
Summative
This is how we’ll formally assess what you have learned in this module.
