At low energies, QCD (quantum chromodynamics) requires non-perturbative solutions. We consider an SU(2) model which is a scaled down version of SU(3), simpler to work with because of its Pauli matrix basis, yet retaining key features such as its being a non-abelian theory. A compactified SU(2) gauge theory may be written as an O(3) vector model; within this context we find an exact non-perturbative solution using a saddle point analysis, making use of an already known Jacobian.
