英文摘要: In this paper, we try to provide a direct method for calculating quark number susceptibility at finite chemical potential and zero temperature. In our approach, quark number susceptibility is totally determined by G[mu](p) (the dressed quark propagator at finite chemical potential mu). By applying the general result given in Phys. Rev. C 71, 015205 (2005), G[mu](p) is calculated from the model quark propagator proposed in Phys. Rev. D 67, 054019 (2003). From this the full analytic expression of quark number susceptibility at finite mu and zero T is obtained.
