Jets in Leptoproduction from QCD
If quarks and gluons are confined, the best way to “see” them is to study the jets of particles. However, while the domain of perturbative QCD has greatly expanded for the last few years, the precision of its predictions has certainly suffered from our lack of methods to handle the non-perturbative features of the theory. In the following, we shall study what perturbative QCD can predict, and also what it cannot. So far, the rule of the game is to find tricks which eliminate non-perturbative effects as much as possible.
