在规范介导的超对称破缺的背景下，我们提供了一个简单的解决\ensuremath{\mu}和强$\mathrm{CP}$问题的方法。动力学超对称破缺中的$R$对称性的普遍出现被用来实现Peccei-Quinn对称性。可接受的\ensuremath{\mu}和$B$条款，以及大的对称性破缺规模的存在下诱导nonrenormalizable相互作用。这个方案的宇宙学后果是对PQ对称性破缺标度和信使或重夸克的数量产生限制。引入非$R$ Peccei-Quinn对称的复杂性与$R$对称的情况进行了对比。
We provide a simple solution to the \ensuremath{\mu} and strong $\mathrm{CP}$ problems in the context of gauge mediated supersymmetry breaking. The generic appearance of $R$ symmetry in dynamical supersymmetry breaking is used to implement Peccei-Quinn symmetry. Acceptable \ensuremath{\mu} and $B$ terms as well as the large symmetry breaking scale are induced in the presence of nonrenormalizable interactions. The cosmological consequences of this scheme turn out to yield constraints on the PQ symmetry breaking scale and the number of the messenger or heavy quarks. The complexity in introducing non-$R$ Peccei-Quinn symmetry is contrasted with the case of $R$ symmetry.
