On the Q-Q channel interaction of the effective NJL-Hamiltonian

Technical Report:

Abstract

We take the usual simple form of the Nambu-Jona-Lasinio (NJL) Hamiltonian containing only the scalar and pseudoscalar terms with two flavours of massless quarks (u and d). Then making the interaction strength position dependent, as done by Bernard et al., to bringing confinement, we calculate the nucleon (N) and delta ({Delta}) masses. In this simple form the interaction seems not to contain enough spin-isospin dependence to yield a reasonable value of N - {Delta} mass difference. The raises doubts if the NJL interaction, in its simple form, can be employed to study the spectroscopic properties of hadrons. (author). 13 refs, 1 fig., 2 tabs.
