  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 4-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 certain functional
basis. We found that the nucleon wave function displays strong diquar
correlations, unlike that for Delta (decuplet) baryon. We also calculate
3-quark-5-quark admixture to baryons, and the resulting antiquark sea PDF.
