Title: Exploring Exotic Matter Across Experiments - An Experimentalists View
The field of non-perturbative QCD continues to pose intriguing challenges, particularly in understanding the complex spectrum of light mesons. Among these, the search and identification of so-called exotic states exceeding the simple quark picture —such as glueballs, hybrids, and tetraquarks—remains a priority. These states hide themselves in the spectrum of broad, interfering and overlapping resonances, populating the light hadron spectrum or appear among the zoo of exotic charmonium resonances.
As an experimentalist, it is obvious to me that advancing our understanding of the hadron spectrum requires not only superior facilities and detectors but also an approach utilizing different beams and production processes to tackle the open problems of understanding the strong interaction. Addressing this challenge requires actually a collaborative approach, combining different experimental data with advanced analysis techniques, called coupled channel analyses.
The talk will discuss these, thereby integrating information from different production mechanisms. New software advancements complement this effort. A brief overview of the recent experimental indications of exotic hadrons will be provided in the talk. Special focus is put on specific ideas to study and hopefully pin down exotic matter. In conclusion, an outlook will be given towards unique possibilities at future and upgraded facilities.
