Summary
Two decades ago, the eld of strongly interacting particles entered a golden age with the discovery of exotic hadrons labeled as XYZs. The breakthrough fueled a surge in experimental research, uncovering dozens of states that appear to lie outside the conventional quark model, although some still require experimental conrmation. The plethora of new states has sparked intense theoretical investigations into new forms of matter, such as quark-gluon hybrids, mesonic molecules, and tetraquarks, making it one of the most signicant open problems in particle physics. Despite the progress, unresolved patterns of masses, decays, and transitions above open-avor thresholds persist and have deepened the mystery surrounding these exotics. The intriguing details of production and suppression observed in heavy ion collisions elevated the importance of these studies to probe their nature.
With EFT-XYZ I intend to develop for the rst time, a comprehensive and unied description of these exotics rooted in quantum eld theory, going beyond existing models. On the basis of scales separation, I construct a general nonrelativistic effective eld theory treatment. Scale factorization introduces systematicity and simplicity allowing model independent predictions. The dynamics contained in the nonperturbative low energy correlators is addressed with new and tailored lattice QCD computational tools. By using an open quantum system framework and lattice QCD input, the effective eld theory can describe the XYZ production in heavy ion collisions. EFT-XYZ is poised to make breakthroughs in calculating the properties, dynamics, and interactions of the XYZ in various environments. It holds the promise to unravel the nature of these new states having impact on both experiments and our understanding of strongly correlated systems, with interdisciplinary implications to other elds. EFT-XYZ success is related to the recent advancement in the aforementioned elds in which I played a pivotal role.
