87984 - PHENOMENOLOGY OF THE STANDARD MODEL

Course Unit Page

Academic Year 2020/2021

Learning outcomes

At the end of the course the student will acquire a good knowledge of the most significant and up-to-date topics of the Standard Model of Particle Physics, through a phenomenological approach. In particular, the student will go through basic experimental searches related to the electroweak and QCD sectors. The student will also acquire an overview of the main experimental results and of new challenges, integrating the notions acquired in other courses.

Course contents

-- MODULE 1:

– Weak interactions:

Charged weak currents and V-A theory

Absence of FCNC

The GIM mechanism

Discovery of the J/psi,tau and Upsilon.

– Electroweak Interactions:

Glashow-Weinberg-Salam model

Discovery of the weak neutral current

Measurements of the Weimberg angle

Electroweak intereference at PETRA

Discovery of the W and Z Boson

Precision tests of the Standard Model at LEP

Electroweak results at the LHC

Phenomenology and experimental evidences of QCD in e+e- collisions: asymptotic freedom and confinement, alfa_s running and jets

QCD in extreme conditions: Ultrarelativistic Heavy Ion Physics at the LHC.

 

-- MODULE 2:

(Brout-Englert-Hagen-Guralnik-Kibble-) Higgs boson: experimental searches and evidence.

Phenomenology of the proton-proton collisions at LHC:

Examples of experimental measurements of particular interest. Searches for experimental indications of new physics beyond the Standard Model (SUSY, GUTs, extra dimensions, etc.).


Physics at future colliders
- High luminosity LHC: HL-LHC
- Future circular colliders: FCC-ee, FCC-hh, CEPC
