    "abstract": "Mesons are made of quark-antiquark pairs held together by the strong force.\nThe one channel spectator, Dirac, and Salpeter equations can each be used to\nmodel this pairing. We look at cases where the relativistic kernel of these\nequations corresponds to a time-like vector exchange, a scalar exchange, or a\nlinear combination of the two. Since the model used in this paper describes\nmesons which cannot decay physically, the equations must describe stable\nstates. We find that this requirement is not always satisfied, and give a\ncomplete discussion of the conditions under which the various equations give\nunphysical, unstable solutions.",
