论文摘要
我们重新审视最小的nambu-goldstone（NG）希格斯超对称（SUSY）SU（5）大统一模型，并研究其现象学的含义。该模型的希格斯扇区具有一个全局的SU（6）对称性，该对称性被自发损坏，并导致最小SUSY标准模型（MSSM）的Higgs Doublets作为NG手性超级场景。因此，该模型自然会导致光线双重击子，并解决Doublet-Triplet分裂问题。由于SU（6）对称性，因此希格斯扇区的耦合受到严格的限制，因此模型比最小的Susy Su更具预测性（5）。我们通过按统一量表的量规耦合常数的匹配条件来确定所有宏大的理论参数，并计算质子寿命，并与当前的实验界面面对面。我们讨论该模型与受约束的MSSM不相容，而在高规模的SUSY方案中，它具有较大的可行参数空间。 Higgs场的三连耦合上的扰动条件对Wino（Gluino）质量施加了上限（下）限制，这意味着这些Gauginos的分层质量模式。未来的质子搜索搜索可以探究参数空间的很大一部分，尤其是如果SUSY破坏量表为$ \ lyssim 100 $ 〜tev。
We revisit the minimal Nambu-Goldstone (NG) Higgs supersymmetric (SUSY) SU(5) grand unified model and study its phenomenological implications. The Higgs sector of the model possesses a global SU(6) symmetry, which is spontaneously broken and results in the Higgs doublets of the minimal SUSY Standard Model (MSSM) as NG chiral superfields. Therefore, the model naturally leads to light Higgs doublets and solves the doublet-triplet splitting problem. Because of the SU(6) symmetry, the couplings of the Higgs sector are tightly restricted, and thus the model is more predictive than the minimal SUSY SU(5). We determine all the grand-unified-theory parameters via the matching conditions of the gauge coupling constants at the unification scale and calculate proton lifetime, confronting this with current experimental bounds. We discuss that this model is incompatible with the constrained MSSM, whilst it has a large viable parameter space in the high-scale SUSY scenario. The perturbativity condition on the trilinear coupling of the adjoint Higgs field imposes an upper (lower) limit on the wino (gluino) mass, implying a hierarchical mass pattern for these gauginos. Future proton-decay searches can probe a large part of the parameter space, especially if the SUSY-breaking scale is $\lesssim 100$~TeV.
