Title: Exotic Quarkonia in Effective field theory
Abstract: Since the early days of QCD the existence of hadrons beyond the quark model baryons and mesons has been foreseen.
These states have now been unambiguously observed in the quarkonium spectrum close and above open flavor thresholds
and are usually referred to as exotic quarkonium. A large variety of models have been put forward to explain these states
but no model has been able to provide a unified description of all the exotic quarkonium states. Furthermore these models have no clear connection to QCD.
As in standard quarkonium, effective field theories can be used to relate the phenomenological descriptions to QCD.
In this talk I will present the development of such an effective field theory framework that, together with lattice QCD inputs,
can be used to describe all the exotic quarkonium states and can also be extended to other double heavy hadrons regardless if they are exotic.
Afterwards I will review the application of this EFT framework to the hybrid quarkonium spectrum including hyperfine contributions
and to the study of hybrid to standard quarkonium transitions.
