N and Δ baryon resonances in constituent quark model

The mass spectra of N and Δ resonances is studied within the framework of a constituent quark model, the confinement potential is assumed as a combination of coulomb like term, a linear confining term plus a harmonic oscillator potential, the results of mass spectra of N and Δ resonances is found to be in excellent agreement with the experimental values reported by particle data group over other theoretical model predictions.
