Abstract: We use the Nambu-Jona-Lasinio (NJL) model to study the structure of mesons and baryons with particular attention given to an interpretation of the scalar-isoscalar (sigma) meson that plays an important role in nuclear structure studies and in the description of nucleon-nucleon scattering. To carry out this program, we generalize the NJL model to include the description of confinement. We also study nucleon structure based upon a quark-diquark model of the nucleon. It is found that scalar (T = 0) diquark and the axialvector (T = 1) diquark contribute approximately equal amplitudes in the nucleon wave function.
