Non-Perturbative Particle Theory and Experimental Tests (Johns Hopkins Workshop on Current Problems in Particle Theory//Proceedings)

The 20th Johns Hopkins Workshop on current problems in particle theory took place in Heidelberg. The topic of the workshop was chosen in view of the success enjoyed by the standard model of electroweak and strong interactions. Precision tests have been dominantly performed in the high-energy domain, where the QCD coupling constant is small enough to allow for a perturbative treatment of the strong interaction. It is therefore very important to consider also the low-energy region for which non-perturbative aspects of QCD come into play.
