| 英文摘要 | The S-wave pi pi scattering lengths a(o) and a(2) are calculated to the lowest order of 1/N-c expansion in the general framework of SU(2) NJL model beyond mean-field approximation. It is shown that using the universal curve of a(o) and a(2) the four NJL parameters, i.e., the current quark mass m(o), the four fermion coupling constant G, the quark momentum cut-off Lambda(f) and the meson momentum cut-off Lambda(b), also the S-wave pi pi scattering lengths in NJL model can be determined.
