The social life of quarks — •Marek Karliner — School of Physics and Astronomy, Tel Aviv University, Tel Aviv, Israel

In the recent years experiments in high energy accelerators have discovered a large number of unusual heavy "cousins" of the proton, i.e. strongly-interacting particles, collectively known as hadrons. Ordinary hadrons are either baryons, containing three quarks, or mesons containing a quark and an anti-quark. The new unusual hadrons contain either two quarks and two antiquarks, in which case they are known as tetraquarks, or four quarks and an antiquark, and are known as pentaquarks. They are often referred to as multiquark, or exotic hadrons. With the large number of such exotics discovered so far, it becomes increasingly important to discuss what additional multiquark states are likely to be observed and how are quarks organized in these exotic hadrons. In my talk I will discuss both questions, providing some guidelines about essential differences between the two types of exotics.
