Brazilian-German WE-Heraeus-Seminar — Hadron Spectroscopy and the New Unexpected Resonances

In the Standard Model of particle physics, all the forces that make up the different interactions show basically the same behavior, with a force proportional to the inverse-square of the distance. The proper sets of theories are called gauge theories. The strong interaction, however, is different from the other interactions due to its non-perturbative character and the still unexplained confinement of quarks and gluons and dynamical mass generation in hadrons. To explore these fundamental questions in the fascinating and not well-understood strong sector of the Standard Model is at the heart of hadron physics and of this workshop.
