FYSS4556 QCD:n h盲iri枚teoria (7 op)
Osaamistavoitteet
At the end of this course, students will be able to deal with the SU(3) color algebra and compute color factors for various quark and gluon scatterings. Students will be able to compute perturbative QCD cross sections, correctly dealing with physical gluon polarization states, and define and apply parton distribution functions in collinearly factorized NLO perturbative QCD cross sections. They will be able to solve DGLAP scale evolution equations and compute cross sections for deep inelastic scattering (DIS) and Drell-Yan process in leading and next-to-leading order, and for jets in leading-order perturbation theory. They will also be able to compute decay widths of quarkonia using perturbative QCD in a non-relativistic limit.
