The discovery of a new particle with the right properties to be the so-called ‘Higgs boson’ at the LHC last year was a further confirmation that the Standard Model formulation, with the spontaneous breaking of the Electro-Weak symmetry, is indeed a good description of Nature. Consequently, this year’s Nobel Prize in Physics was awarded to François Englert and Peter Higgs “for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN’s Large Hadron Collider”.

In this lecture I will try to give an overview, at a very basic level, of the main technical ideas that underline the BEH mechanism: what mass means, what symmetry breaking means, what gauge symmetries are, and finally what happens when combining the latter two ingredients…

It is a simple repetition of the lecture I gave in November to allow more people to attend.
The talk is intended for our genius students, but everybody is welcome.

Here are some problems for you to work on after the lecture.
