SummaryThe first part of the QCD course builds upon the knowledge acquired in Relativistic QFT to compute tree-level cross sections, and applies it to collider physics applications. The second part of the course lays the foundations of Lattice QCD.
Course description - Local gauge invariance, QCD Lagrangian, Feynman rules.
- Colour algebra, colour Fierz identity, the double-line notation, the large Nc limit
- Spinor helicity method; tree-level amplitudes; recursion relations.
- The beta function and the running coupling constant.
- e+e- annihilation to hadrons: total cross sections; jet cross sections; infrared safety, event shape variables.
- Deep inelastic scattering structure functions, collinear factorization, parton density functions, splitting functions, scaling violation and the Altarelli-Parisi equations.
- Drell-Yan and Higgs production.
- Why we need non-perturbative methods in QCD [large coupling and RG argument for hadron masses].
- Relation between QM in imaginary time and equilibrium statistical mechanics, the transfer matrix.
- Scalar fields on the lattice: action, classical continuum limit, path integral for free lattice scalar field, the "boson determinant", continuum limit obtained at continuous phase transitions, universality.
- Fermion fields on the lattice: naive+doubling, Wilson, staggered, Nielsen-Ninomiya theorem, domain-wall/overlap/Ginsparg-Wilson. Fermion path integral, fermion determinant, pseudofermions.
- Gauge fields on the lattice: Wilson action, classical continuum limit, strong coupling expansion - string tension and glueball masses. Inclusion of fermions - hopping parameter expansion. Weak coupling expansion, lambda parameters. (Anomalies?)
- QCD on the lattice: two-point hadron correlators - masses and decay constants; three-point hadron correlators - matrix elements, form factors. Examples: semileptonic decays, neutral kaon mixing.
- Numerical techniques: Markov Chain Monte Carlo - Metropolis-Hastings for pure QCD (and quenched approximation); Hybrid Monte Carlo for full QCD. Critical slowing down in continuum and chiral limits - topological charge.
