LernzielWith this course the students will receive a detailed introduction to the physics of the Higgs boson in the Standard Model. They will acquire the necessary theoretical background to understand the main production and decay channels of the Higgs boson at high-energy colliders, and the corresponding experimental signatures.
InhaltTheory part:
- the Standard Model and the mass problem: WW scattering and the no-lose theorem
- the Higgs mechanism and its implementation in the Standard Model
- radiative corrections and the screening theorem
- theoretical constraints on the Higgs mass; the hierarchy problem
- Higgs production in e+e- collisions
- Higgs production at hadron colliders
- Higgs decays to fermions and vector bosons
- Higgs differential distributions, rapidity distribution, pt spectrum and jet vetoes
- Higgs properties and beyond the Standard Model perspective
- Outlook: The Higgs sector in weakly coupled and strongly coupled new physics scenarios.

Experimental part:
* Introductory material:
- reminders of detectors/accelerators
- reminders of statistics: likelihoods, hypothesis testing
- reminders of multivariate techniques: Neural Networks, Decision Trees
* Main topics:
- pre-history (pre-LEP)
- LEP1: measurements at the Z-pole
- LEP2: towards the limit mH<114 GeV
- TeVatron searches
- LHC:
-- main channels overview
-- dissect on analysis
-- combine information from all channels
-- differential measurements
-- off-shell measurements
- Future:
-- pseudo-observables / EFT
-- Beyond Standard Model
