16 Apr 2007, 16:00 → 19 Apr 2007, 18:00 Europe/Brussels

e.349

I will introduce the idea of the Higgs as a composite pseudo-Goldstone boson, discuss its theoretical motivations and its phenomenological consequences.

Monday, 16 April

Lecture I

The need of an EWSB sector: WW scattering and unitarity. The case of a
fundamental Higgs. The hierarchy problem.

Tuesday, 17 April

Lecture II

A non-linear EWSB sector: analogy with the pions in QCD. Technicolor: a short
account.

Wednesday, 18 April

Lecture III

The composite Higgs: an SO(5)/SO(4) minimal model. WW scattering. The Higgs
potential: gauge contribution. Analogy with the electromagnetic correction to the
pion mass in QCD.

Thursday, 19 April

Lecture IV

Linear couplings for the fermions. The Higgs potential: top quark contribution.
Partial compositeness and its implications for the LHC.
