Seminar: Propsects in Hadron Spectroscopy

Thursday 30 November 2017 from 14h30 to 15h30
Many hadrons, particles undergoing the strong nuclear interaction, were discovered during the 20th century. Their properties are now well known and understood. These particles are non- elementary. They are resonances composed of either three quarks, or either a quark-antiquark pair. The theory of the strong nuclear interaction, the quantum chromodynamics (QCD), governs the interactions of quarks via the exchange of gluons. QCD predicts the existence of other resonances, whose compositions are distinct from well-known resonances. Identifying and studying the properties of these “exotic hadron” is one of the remaining challenges in nuclear physics.
New experiments in America (GlueX), Europe (LHCb) and Asia (BESIII) are currently running to find experimental evidence of such exotic resonances. Recently a theoretical and experimental collaboration, the Joint Physics Analysis Center (JPAC), have been created to develop the necessary theoretical tools for the analysis of these forthcoming coming data sets. In this talk we will see what are the possible experimental signs of exotic resonances and what are the techniques to identify them.
