Strong interaction at Hadronic Colliders
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
- General reminder : quarks, QCD Lagrangian, chiral symmetry and quark condensate, αs running, CKM matrix
- Sea of quarks and gluons : Parton Distribution Function PDF ; Deep Inelastic Scattering ; Evolution equations : DGLAP, BFKL ; Nuclear PDF ; Colour Glass Condensate
- Hadronisation and jets : factorisation theorem ; hadronisation : fragmentation functions, coalescence ; underlying event, multi-parton interactions ; jet reconstruction
- Part B – Physics of Quark-Gluon Plasma (QGP)
- Concepts of a QGP : phase diagram, Bjorken scenario, measured thermodynamic parameters
- QGP in experiments : experimental facilities, colliding systems (pp, pA, AA), basic observables
- QGP signatures : hadrochemistry of light-quark flavour (u,d,s), hydrodynamics, heavy-quark flavours (c,b), in-medium energy losses
- Modern experiments in heavy-ion physics (detector considerations and details)
- Data analysis : one concrete case
