Description
Content
In this course, we will introduce light-front quantization as an alternative formulation for quantum field theories, in particular QCD, and show how to derive the light-front version of the Feynman rules for QCD. We will then present several applications of this formalism, in particular in the context of QCD at high energy (or equivalently low Bjorken x), such as the dipole factorization for deep inelastic scattering, or the hybrid factorization for forward particle production in proton-nucleus collisions.
Completion methods
attendance in lectures, solving exercise problems
Learning outcomes
From this course, the student will gain an elementary understanding of the light-front quantization of QCD, and will be able to perform tree-level calculations in light-front perturbation theory. He will also have a basic knowledge of low x QCD and gluon saturation, allowing him to explore further the literature in that field.
Description of prerequisites
Quantum mechanics and elementary particle physics. Suitable for advanced Master’s students and upwards.
