Abstract
These lectures present an introduction to the study of scalar and tensor mesons, with an emphasis on an introduction to the phenomenology of spectroscopy. Specifically I examine why one uses Breit-Wigner resonance functions to characterize the parameters of the particles, and how the simple function must be modified, sometimes dramatically, in order to understand and interpret the experimental results. I apply this to the lowest mass tensors, where the situation is well understood, then to the scalars, showing that the quark model can account for the observed scattering in both cases. I then study some recent results leading to the conclusion that non quark model states clearly exist.
