大统一对手征前子模型的限制

RESTRAINTS FROM GUT ON CHIRAL THREEPREON MODEL

本文由WNW条件出发,分析了大统一对禁闭弱作用手征前子模型的限制.我们发现超色群不能是SU(N)群及SO(M)群,而半单群SU(N)×SO(M)及SU(N)×SU(M)作为超色群是可行的.通过重整化群计算,得到在合理的能标10^(14)GeV≤A_u≤10^(19)GeV及300GeV≤A_(MC)≤1TeV下,可能的候选者是:G_(MC)=SU(3)×SO(5)及G_U≥SU(11);G_(MC)=SU(3)×SU(2)及G_U≥SU(12).

According to WNW condition, a systematic analysis about the restraints from GUT on chiral three-preon model with confining weak interaction is discussed. It shows that the metacolor gauge group may not be SU(N) or SO(M), but may be semisimple group, for example, SU(N)×SO(M) or SU(N)×SU(M). By calculating, the candidats are G_(MC)=SU(3)×SO(5) and G_U≥SU(11), G_(MC)=SU(3)× SU(2) and G_U≥SU(12) under conditions: 10^(14)GeV≤Λ_U≤10^(19) GeV and 300GeV≤ Λ_(MC)≤1TeV.
