A unified potential for mesons and baryons

We examine several phenomenological nonrelativistic$$q\bar q$$ potentials, with different radial dependences, that fit the low-lying charmonium spectra. With the familar Coulomb-plus-ramp-type dependence the same potential can reproduce the spectra of the light mesons using the Schrödinger equation. With half-strength and the addition of a small three-body term the ground states of the baryons are also obtained.
