Description
The discovery of XYZ exotic states in the hadronic sector, particularly those containing two heavy quarks, remains one of the most intriguing open problems in particle physics. In this talk, I present the Born-Oppenheimer Effective Field Theory (BOEFT), a framework derived from QCD, capable of describing exotic hadrons of any composition. I present results on the key nonperturbative gauge-invariant correlators to be computed on lattice QCD—such as static energies, generalized Wilson loops, gluelumps, and adjoint mesons—for understanding the patterns of XYZ states. Moreover, I show for the first time new results on the behavior of static energies at short distances and mixing with the threshold at long distances based on BOEFT. As an application, I show results for the hybrid spectrum, hybrid decays to quarkonium, results for X(3872) and T_cc (3875), and pentaquark states.
