What is the hidden symmetry in the electroweak theory

Reference no: EM131352578

1. What is the hidden symmetry in the electroweak theory? In answering this it may be useful to recall the Yang-Mills theory and the role of the Higgs boson.

2. Before the electroweak theory it was difficult to compare the weak coupling constant to the electromagnetic one because they have different dimensions. Explain these dimensions and how the electroweak theory gives an appropriate strength to a dimensionless weak coupling constant.
