    "abstract": "Hadron spectra and other properties of quark systems are studied in the\nframework of a non-relativistic spin-independent phenomenological model. The\nchosen confining potential is harmonic, which allowed us to obtain analytical\nsolutions for both meson and baryon (of equal constituent quarks) spectra. The\nintroduced parameters are fixed from the low-lying levels of heavy quark\nmesons. The requirement of flavor independence is imposed, and it restricts the\npossible choices of inter-quark potentials. The hyper-spherical coordinates are\nconsidered for the solution of the three-body problem.",
