Overview: In this lecture we describe the experimental evidence for the existence of quarks and gluons conﬁned in hadrons (nucleons and mesons). We derive from the so-called “naive” quark model predictions for measurable quantities such a particle masses or angular distributions in scattering or decays, and compare with experiments. It is assumed that the students have the relevant knowledge from the introductory (bachelor level) courses in nuclear, particle and atomic physics. If required the course will be given in English.
