Description

Strong interaction at hadron colliders
Experimental approach of Quantum Chromodynamics (QCD), especially as seen at hadronic colliders of high energy, like LHC

• Part A – Typical aspects of QCD

1. General reminder : quarks, QCD Lagrangian, chiral symmetry and quark condensate, αs running, CKM matrix
2. Sea of quarks and gluons : Parton Distribution Function PDF ; Deep Inelastic Scattering ; Evolution equations : DGLAP, BFKL ; Nuclear PDF ; Colour Glass Condensate
3. Hadronisation and jets : factorisation theorem ; hadronisation : fragmentation functions, coalescence ; underlying event, multi-parton interactions ; jet reconstruction

• Part B – Physics of Quark-Gluon Plasma (QGP)

1. Concepts of a QGP : phase diagram, Bjorken scenario, measured thermodynamic parameters
2. QGP in experiments : experimental facilities, colliding systems (pp, pA, AA), basic observables
3. QGP signatures : hadrochemistry of light-quark flavour (u,d,s), hydrodynamics, heavy-quark flavours (c,b), in-medium energy losses
4. Modern experiments in heavy-ion physics (detector considerations and details)
5. Data analysis : one concrete case
