Microscopic structure of magnetic bions

Magnetic bions — stable bound states of monopoles and twisted (“Kaluza-Klein”) anti-monopoles, carrying two units of magnetic charge — have been shown to be the leading cause of confinement and mass gap in four-dimensional gauge theories with massless adjoint fermions compactified on

. In this paper, we study in detail the bion mechanism and the scales involved for an SU(2) gauge group, using traditional QCD instanton methods. We represent the vacuum functional as the partition function of a bion-anti-bion plasma and obtain the next-to-leading dependence of the mass gap on the
