我们提出了一个简单的大统一理论（GUT）方案，其中超对称性（SUSY）自发破缺的可见部门。我们的模型是基于GUT模型，已提出解决几乎所有的问题，在传统的GUT方案。在以前的工作中，这些问题可以通过超对称真空中的自然假设来解决。在本文中，我们考虑模型的扩展（即，省略一个单重场）并且自发地打破SUSY而没有新的扇区。我们的模型没有一个隐藏的部门，并预测高尺度超对称性的sfermion质量是为了100-1000 TeV和风味违反过程被抑制。在这种情况下，我们可以看到一个明确的签名的大统一理论在sfermion质谱，因为sfermion质谱respectsmatter统一。此外，我们还发现了一个超重的长寿命带电轻子作为我们假设的证据，它可能在LHC中出现。
We propose a simple grand unified theory (GUT) scenario in which supersymmetry (SUSY) is spontaneously broken in visible sector. Our model is based on the GUT model that has been proposed to solve almost all problems in conventional GUT scenarios. In the previous work, the problems can be solved by a natural assumption in a supersymmetric vacuum. In this paper, we consider an extension of the model (i.e., omitting one singlet field) and break SUSY spontaneously without a new sector. Our model does not have a hidden sector and predicts high-scale SUSY where sfermion masses are of order 100–1000 TeV and flavor violating processes are suppressed. In this scenario, we can see an explicit signature of GUT in the sfermion mass spectrum since the sfermion mass spectrum respectsmatter unification. In addition, we find a superheavy long lived charged lepton as a proof of our scenario, and it may be seen in the LHC.
