我们研究了构造具有狄拉克-加吉诺质量和规范耦合统一的模型的可能性。我们确定了一个很有希望的模型，并讨论了它可以在多大程度上具有“自然”超对称(SUSY)谱。然后，我们确定了对它的低能量约束，并在统一尺度下提出了一组受约束的边界条件。我们描述了这些边界条件在频谱生成器Sarah中的实现，并执行了参数空间的第一次探索，特别是搜索光谱相对较轻的点。结果表明，与约束最小超对称标准模型的任何期望相比，超对称状态的质量模式是非常不同的。
We examine the possibilities for constructing models with Dirac gaugino masses and unification of gauge couplings. We identify one promising model and discuss to what extent it can have a "natural" supersymmetric (SUSY) spectrum. We then determine the low-energy constraints upon it, and propose a constrained set of boundary conditions at the unification scale. We describe the implementation of these boundary conditions in the spectrum-generator generator SARAH and we perform a first exploration of the parameter space, specifically searching for points where the spectrum is relatively light. It is shown that the pattern of the masses of SUSY states is very different compared to any expectations from the constrained minimal supersymmetric Standard Model.
