The Hidden Charm of Exotic Hadrons

Abstract:

The discovery of mesons composed of four quarks in decays involving charmonia at the B-factories opened a new experimental window that allows to directly observe how effects beyond the quark model lead to the formation of hadronic states. With the discovery of two Pentaquark candidates in their decay to $J/\psi$ proton, LHCb extended this window to the baryon sector. So far the nature of  these states is not fully understood and further progress requires the investigation of their expected complex decay channels. The discovery also raises the question whether there are more such exotic baryons, what kind of multiplet they form, and how to search for further states. The LHC is the only machine where the large samples of heavy baryons required for these studies are produced. Exotic hadrons are exemplary laboratories of the strong interaction. Their analysis will require a close interaction between experiment and theory in order to extract the maximum amount of information and to draw the conclusions required to further the understanding of the hadron spectrum in general.
