We present a separable representation of the chiral quark cluster model nucleon-nucleon potential. The separable interaction is constructed in momentum space, by means of an expansion of the resonating group method kernels in terms of harmonic oscillator wavefunctions. The nucleon-nucleon potential includes Δ-isobar degrees of freedom within a coupled-channel formalism. For the two-body system, it removes the complication of evaluating the potential coming from the quark substructure, being… CONTINUE READING
