论文摘要
我们为基于自发的CP违规而对强大的CP问题提出了超对称解决方案，该解决方案同时解决了超对称性破裂所带来的影响。通过与重型夸克·纳尔逊·巴尔（La Nelson-Barr）互动，将产生的CP违反阶段传达给夸克部门。右手中微子的主要质量是通过与CP违反部门的相互作用而产生的，因此不保留CP。这使中微子部门是一个违反CP的阶段，然后可以通过瘦素来产生宇宙的重子不对称。通过吸引特定的仪表中介模型来自然抑制树级gluino质量的相位，可以抑制超对称性破坏参数中的有问题的阶段。这种抑制以及在量规调中，所有循环产生的风味和违反CP的侵犯均具有最小的风味变化，从而可以完全稳定地解决强大的CP问题。
We present a supersymmetric solution to the strong CP problem based on spontaneous CP violation which simultaneously addresses the affects coming from supersymmetry breaking. The generated CP violating phase is communicated to the quark sector by interacting with a heavy quark a la Nelson-Barr. The Majorana mass of the right handed neutrinos is generated by interactions with the CP violating sector and so does not conserve CP. This gives the neutrino sector a non-trivial CP violating phase which can then generate the baryon asymmetry of the universe through leptogeneis. The problematic phase in the supersymmetry breaking parameters are suppressed by appealing to a particular gauge mediation model which naturally suppresses the phases of the tree-level gluino mass. This suppression plus the fact that in gauge mediation all loop generated flavor and CP violation is of the minimal flavor violation variety allows for a complete and consistent solution to the strong CP problem.
