论文摘要
重力介导的SUSY断裂的新实现与R对称性一致。我们为隐藏领域（Goldstino）超级领域和Kahler电位采用单一超电势术语参数化紧凑型或非紧密的Kahler歧管。它们的标态曲率可能与Goldstino的R电荷有系统地相关，因此可以实现Minkowski溶液。在卡勒电势中，高阶术语对R对称性的轻度违反可以使R轴轴上具有现象学上可接受的质量。在所有情况下，都可以获得非呈现的软susy破裂参数，并通过方便地应用Giudice-Masiero机制来容纳MSSM的MU问题。
New realizations of the gravity-mediated SUSY breaking are presented consistently with an R symmetry. We employ monomial superpotential terms for the hidden-sector (goldstino) superfield and Kahler potentials parameterizing compact or non-compact Kahler manifolds. Their scalar curvature may be systematically related to the R charge of the goldstino so that Minkowski solutions without fine tuning are achieved. A mild violation of the R symmetry by a higher order term in the Kahler potentials allows for phenomenologically acceptable masses for the R axion. In all cases, non-vanishing soft SUSY-breaking parameters are obtained and a solution to the mu problem of MSSM may be accommodated by conveniently applying the Giudice-Masiero mechanism.
