    "abstract": "We present an algebraic U(7) model for baryons which encompasses both\nsingle-particle and collective forms of quark dynamics. The mass operator by\nconstruction preserves the permutation symmetry between identical quarks. The\nunderlying geometric structure of baryons is discussed in terms of a rigid\nrotating and vibrating oblate top shape. The model is applied to the mass\nspectrum of nonstrange baryons.",
