Summary
We propose a nonrelativistic model of heavy-quark interaction mediated by a one-particle exchange, and derive a phenomenological confining potential which is independent of flavor and color of quarks. It contains only one fitting parameter interpreted as mass of the virtual field induced by the strong charge of the exchange particle.
