The strong interaction is the least understood sector of the standard model of particle physics. In the last decade the discovery of exotic mesons, which cannot be explained as quark-antiquark states, has highlighted the rich structure of strongly interacting particles beyond the quark model. Recently two exotic baryons, decaying into a proton and a J/psi have been discovered at the LHCb experiment. These two resonances are compatible with an interpretation as five-quark states and are therefore referred to as pentaquarks. Here a program is proposed to investigate the nature of these exotic particles in detail by exploring new decay modes and searching for members of a pentaquark multiplet.
