在有效场论的框架下,我们考虑了隐扇形规范群中的超对称性破缺和超引力对隐扇形真空角θh的影响。如果U(1)R对称性被分解为一个离散子群Zn,N≥3(N=4是边缘的),则势的θ h参数依赖性产生唯象上可接受的不可见轴子解.反常U(1)超弦模型是解决强CP之谜的不可见轴子的很好的候选者。
In the effective field theory framework, we consider the effect of supersymmetry breaking via gaugino condensation and supergravity in the hidden sector gauge group on the hidden sector vacuum angle θh. The θhparameter dependence of the potential yields phenomenologically acceptable invisible axion solutions if the U(1)Rsymmetry is broken down to a discrete subgroup ZNwith N≥3 (N=4 is marginal). Anomalous U(1) superstring models are good candidates for this invisible axion resolution of the strong CP puzzle.
