SU中的双三重态分裂(5)大统一

Doublet-Triplet Splitting in an SU(5) Grand Unification

Toshifumi Yamashita

摘要:

我们提出了一个新的解决方案,双重三重态分裂的问题,也工作在超对称SU(5)大统一理论,是可测试的TeV级对撞机实验。在我们的模型中,SU(5)对称性通过细谷机制被破缺。由于细谷破缺的相位性质,即使在SU(5)模型中也可以实现“缺失的VEV”。这个解决方案的一个普遍和独特的预测是存在轻伴随手征超多重态的超对称性破缺尺度的质量。虽然这些干扰规范耦合统一,它可以恢复保持统一规范耦合常数微扰通过引入额外的矢量类粒子,这也可能在即将到来的对撞机实验中观察到。

英文摘要:

We present a new solution to the doublet-triplet splitting problem which also works in a supersymmetric SU(5) grand unified theory and is testable at TeV-scale collider experiments. In our model, the SU(5) symmetry is broken through the Hosotani mechanism. Thanks to the phase nature of the Hosotani-breaking, the "missing VEV" can be realized even in an SU(5) model. A general and distinctive prediction of this solution is the existence of light adjoint chiral supermultiplets with masses of the supersymmetry breaking scale. Though these disturb the gauge coupling unification, it can be recovered keeping the unified gauge coupling constant perturbative by introducing additional vector-like particles, which may be also observed in the upcoming collider experiments.
