我们研究了区间上五维(5D)大统一理论(GUTS)的构造，我们称之为iGUT。作为一个例子，我们分析了超对称SO(10)iGUT，其中规范多重态分布在5维体中。通过区间边界条件将SO(10)直接约化为标准模型规范对称性。请注意，这种降阶是不可能的情况下，胆子在奥比诺尔德。根据希格斯场和物质场的位置(大块或薄膜)，有四种可能的情况。我们研究了在每种情况下的规范耦合统一、质子衰变、SO(10)的T-b-tau统一等肠道特征。我们还对味道现象学进行了评论。
We investigate a construction of five-dimensional (5D) grand unified theories (GUTs) on an interval, which we call iGUTs. We analyze supersymmetric SO(10) iGUT as an example, where the gauge multiplet is spread over the 5D bulk. The SO(10) is directly reduced to the standard model gauge symmetry through the interval boundary conditions. Notice that this rank reduction is impossible in case of GUTs on orbifolds. Four scenarios are possible according to locations (bulk or brane) of Higgs and matter fields. We investigate the gauge-coupling unification, the proton decay, the SO(10) GUT features such as t-b-tau unification and so on in each scenario. We also comment on the flavor phenomenology.
