Description
In the past decade a large amount of unexpected states have been discovered in the charmonium and bottomonium spectra. These states are candidates for nontraditional hadronic states including four quarks or gluonic excitations as constituents. Many of these states can be identified as heavy quark-antiquark bound states in gluonic and light-quark static energies. In this talk I elaborate on an effective field theory approach that takes inspiration from the Born-Oppenheimer approximation that can be used to describe these exotic states with input from lattice QCD. Results for the hybrid spectrum including spin-dependent contributions and semi-incusive
decays into quarkonia will be reviewed.
