Description
I will review our recent lattice studies of exotic tetraquark hadrons, in particular those pertinent to recent experimental discoveries. The states that reside above or slightly below threshold have been inferred from the scattering on the lattice. The structure has been extracted by probing the hadrons with the electromagnetic current, which renders the charge distributions of individual quark flavors, and enables distinction between molecular and diquark-antidiquark compositions.
