| 英文摘要 | The analysis based on the renormalized effective potential indicates that, similar to in the 4d two-flavor nambu-jona-lasinio (njl) model, in a 2d two-flavor gross-neveu model, the interplay between the quark-antiquark and the diquark condensates in vacuum also depends on g(s)/h-s, the ratio of the coupling constants in scalar quark-antiquark and scalar diquark channel. only the pure quark-antiquark condensates exist if g(s)/h-s > 2/3, which is just the ratio of the color numbers of the quarks participating in the diquark and quark-antiquark condensates. the two condensates will coexist if 0 < g(s)/h-s < 2/3. however, different from the 4d njl model, the pure diquark condensates arise only at g(s)/h-s = 0 and are not in a possibly finite region of g(s)/h-s below 2/3. |
