QCD_{1+1} with Static Quarks as Supersymmetric Quantum Mechanics
arXiv:hep-th/9802060 · doi:10.1103/PhysRevD.58.027701
Abstract
We reexamine the solvable model problem of two static, fundamental quarks interacting with a SU(2) Yang-Mills field on a spatial circle, introduced by Engelhardt and Schreiber. If the quarks are at the same point, the model exhibits a quantum mechanical supersymmetry. At finite separation, the supersymmetry is explicitly broken in a way which naturally explains the geometrical nature of spectrum and state vectors of this system.
