Description
We show how the Born--Oppenheimer effective field theory (BOEFT)
provides a unified description of ordinary and exotic quarkonia grounded
on the non-relativistic expansions of QCD and supplemented with lattice
QCD inputs. We show applications of the BOEFT to tetraquarks,
pentaquarks, quarkonium hybrids and to assess threshold effects in the
quarkonium spectrum. We present the insights that BOEFT delivers us omn
the mature of these XYZ exotics states.
