Meson spectroscopy: analysis of new and exotic states
A large number of “exotic” experimental discoveries, which did not fit the expectations of the quark model, as well as the unprecedented statistical precision have been obtained by COMPASS, LHCb, BESIII, Belle and other experiments. These discoveries occur especially in the open and hidden charm and bottom sectors, but some of them also correspond to the light quark sector. We propose to perform combined Partial Wave Analyses (PWAs) of the same final state measured in different experiments, making use of the theoretical tools developed in Task1 (all sub-tasks) and Task2 (in particular T2.1 and T2.2).
Task 3 is divided into the following sub-tasks:
