Existence of glueballs in strongly coupled lattice gauge theories

It is shown that the plaquette-plaquette correlation functions in pure lattice gauge theories exhibit an isolated simple pole in the complex energy variable for large-coupling constants. This implies the existence of isolated one-particle (glueball) states in the space of “boxitons”.
