Abstract
The effects of the explicit treatment of multiquark confined states in the quark potential model are studied for the two-nucleon system. The confined six-quark component in the nucleon-nucleon wave function is shown to generate a new mechanism for the short-range nucleon-nucleon interaction which qualitatively reproduces both the repulsion and medium range attraction properties of the nuclear force. A quantitative effect of this mechanism is studied for a model with harmonic oscillator confinement. It is found that for an appropriate choice of parameters the NN force generated by an admixture of multiquark confined states can bind the six-quark system in the shallow deuteron-like bound state and qualitatively reproduces the low-energy phase-shift behavior. Our results may also be considered as the first example of dynamical calculations of nucleon-nucleon scattering in the Quark Compound Bag method using the explicit form of the six quark Hamiltonian.
