abstract: On the AdS 5 cone, conformally compactified to R 1⊗S 3, a quark-diquark model of light flavor baryons is developed. The system on this manifold is described in terms of a scalar conformal equation, gauged by the field of a D3 brane whose transversal dimensions have been conformally wrapped over R 1⊗S 3. Such a system does not result exactly conformally invariant because the gauge potential slightly modifies the conformal centrifugal barrier of the free geodesic motion. Thanks to this, the model describes the correct mass ordering in the P 11-S 11 pairs through the spectra as a combined effect of conformal symmetry breaking, on the one side, and a parity change of the diquark from a scalar at low masses, to a pseudoscalar at higher masses, on the other. We calculate the number of resonances with masses below 2500 MeV needed for the completeness of the above scheme and find a total of 32 missing nucleon and states. Their absence or presence in the respective spectra relates to the degree to which conformal symmetry is realized in the lightest flavor sector. The scheme also allows for a prediction of the dressing function of an effective instantaneous gluon propagator from the Fourier transform of the gauge potential. We find a dressing function that is finite in the infrared and tends to zero at infinity. © 2011 American Institute of Physics.
