N2 - We calculate light-front wave functions of mesons, baryons and pentaquarks in a model including constituent mass (representing chiral symmetry breaking), harmonic confining potential, and four-quark local interaction of 't Hooft type. The model is a simplified version of that used by Jia and Vary. The method used is numerical diagonalization of the Hamiltonian matrix, with a certain functional basis. We found that the nucleon wave function displays strong diquark correlations, unlike that for the Delta (decuplet) baryon. We also calculate a three-quark-five-quark admixture to baryons and the resulting antiquark sea parton distribution function.
