Title

What are the questions?

Gauge theories (like electromagnetism) describe fermions (quarks) which carry an SU(3) charge (color) and interact through the exchange of vector bosons (gluons)

Second and third generations of quarks and leptons are much more massive

In the Standard Model (Glashow, Weinberg, Salam, ‘t Hooft, Veltmann)

Fundamental parameters of Standard Model (SM)

Theoretical problems

Standard Model works at the 10-3 level and would be completed by the discovery of the Higgs, but the Higgs may be the first window on to a new domain of physics at the electroweak scale

Introduce a symmetry between bosons and fermions:

Accelerator = Microscope
