标题： Dynamical Relaxation of the Supersymmetric CP Violating Phases

摘要： 一种超对称的Peccei-Quinn机制的推广被提出，在其中超对称标准模型中的两个U(1) CP破坏相被提升为动态变量。 这相当于假定在超对称破缺部分存在自发破缺的全局对称性。 然后真空可以接近一个CP守恒点。 作为结果，强CP问题和超对称CP问题可能通过类似的机制得到解决。 显示英文摘要

摘要： A supersymmetric generalization of the Peccei-Quinn mechanism is proposed in which two U(1) CP violating phases of the supersymmetric standard model are promoted to dynamical variables. This amounts to postulating the existence of spontaneously broken global symmetries in the supersymmetry breaking sector. The vacuum can then relax near a CP conserving point. As a consequence the strong CP and supersymmetric CP problems may be solved by similar mechanisms.
