Heavy hybrids and tetraquarks in effective field theory

Blog Article

We report on Covert an effective field theory (EFT) description of exotic quarkonia as bound states on the spectrum of hybrid and tetraquarks static energies.We provide expressions for hybrid and tetraquarks static energies in terms of Wilson loops.The former have been computed in quenched lattice calculations but the latter are yet unavailable.

From the few simulations with Spatula dynamical light-quarks we argue that the overall picture from hybrid static energies does not change but additional states, such as heavy meson pairs, need to be considered for a full description.In this EFT framework for quarkonium hybrids, we report on recent results for mixing with standard quarkonium, spin-dependent contributions, and semi-inclusive decays.
