Abstract
One of the open challenges in subnuclear physics is to understand the non-perturbative
regime of Quantum chromodynamics, including the world of the nucleon and its excitations.
One of the key issues here is to identify the relevant degrees-of-freedom and the eective forces
between them. A necessary step towards this aim is a precise knowledge of the experimental
spectrum and the properties of baryon resonances. Light baryon resonances are investigated
by several experiments worldwide. In the talk, among other results recent double polarisation
experiments at ELSA, JLAB and MAMI will be discussed.
