| 英文摘要 | The color number n-c-dependence of the interplay between quark-antiquark condensates <(q) over barq > and diquark condensates < qq > in vacuum in two-flavor four-fermion interaction models is researched. the results show that the g(s)-h-s (the coupling constant of scalar((q) over barq)(2)-scalar (qq)(2) channel) phase diagrams will be qualitatively consistent with the case of n-c=3 as n-c varies in 4d nambu-jona-lasinio model and 2d gross-neveu (gn) model. however, in 3d gn model, the behavior of the g(s)-h-p (the coupling constant of pseudoscalar (qq)(2) channel) phase diagram will obviously depend on n-c. the known characteristic that a 3d gn model does not have the coexistence phase of the condensates <(q) over barq > and < qq > is proven to appear only in the case of n-c <= 4. in all the models, the regions occupied by the phases containing the diquark condensates < qq > in corresponding phase diagrams will gradually decrease as n-c grows up and finally go to zero if n-c -> infinity, i.e. in this limit only the pure <(q) over barq > phase could exist. |
