我们研究了与 N = 1 超引力耦合的超对称理论中的 Peccei-Quinn 对称性 U(1)PQ。 U(1)PQ 被认为是超势的通常全局对称性，而不是被超重力引起的软超对称破缺明确破坏的 R 对称性。 U(1)PO 断裂的尺度为 MPQ∼MPlanck× exp ( −4π λ2)∼108−12GeV ，由软超对称断裂的对数演化确定。
We investigate the Peccei-Quinn symmetry U(1)PQin supersymmetric theories coupled to N = 1 supergravity. U(1)PQis identified with a usual global symmetry of the superpotential, rather than an R-symmetry which is explicitly broken by the soft supersymmetry breakings induced by supergravity. The scale of U(1)PObreaking is found to be MPQ∼MPlanck× exp ( −4π λ2)∼108−12GeV , as determined by the logarithmic evolution of soft supersymmetry breakings.
