We present a grand unified theory (GUT) that has GUT fields with masses of the order of a TeV, but at the same time preserves (at the one-loop level) the success of gauge-coupling unification of the minimal supersymmetric standard model (MSSM) and the smallness of proton decay operators. This scenario is based on a five-dimensional theory with the extra dimension compactified as in the Randall-Sundrum model. The MSSM gauge sector and its GUT extension live in the 5D bulk, while the matter sector is localized on a 4D boundary.the is a test again
我们提出了一种大统一理论（GUT），其大统一场的质量约为1 TeV，但同时（在单圈水平上）保留了最小超对称标准模型（MSSM）规范耦合统一的成功以及质子衰变算符的微小性。这种情形基于一个五维理论，其中额外维度如兰德尔-桑德鲁姆模型那样紧致化。MSSM规范部分及其GUT扩展存在于五维体空间中，而物质部分局域在一个四维边界上。这又是一次检验
