Description
I present the Born-Oppenheimer effective field theory description of quarkonia, hybrids, tetraquarks and pentaquarks. The EFT relies uniquely on symmetries, systematic expansions in some small parameters and lattice QCD input.The talk is mostly based on Phys.Rev.D 110 (2024) 9, 094040 and 2411.14306.
