极小$R$ -对称模型中弱伴随标量的唯象性研究

Exploring the phenomenology of weak adjoint scalars in minimal $R$-symmetric models

Linda M. Carpenter, Matthew J. Smylie

摘要:

我们研究的现象学的标量场在弱和希格斯部门的最小$R$对称模型,特别是“swino”和“sbino”,标量合作伙伴的手征领域结婚的电弱规范玻色子在狄拉克高根诺模型。这些字段是$SU(2)$和$U(1)$的伴随表示,并且具有$CP$ -偶数分量和$CP$ -奇数分量。这些新的状态的相互作用进行了总结,和衰变宽度计算分析到一个循环的顺序。我们讨论了这些新态对MSSM超费米子质量谱的树级贡献。我们还探讨了生产截面和衰变签名在对撞机几个选定的基准。我们发现,参数空间的大区域不受当前对撞机数据的约束。

英文摘要:

We examine the phenomenology of the scalar fields in weak and Higgs sectors of minimal $R$-symmetric models, in particular the 'swino' and 'sbino', the scalar partners to the chiral fields that marry the electroweak gauge bosons in Dirac gaugino models. These fields are in adjoint representations of $SU(2)$ and $U(1)$ and have both $CP$-even and $CP$-odd components. The interactions of these new states are summarized, and decay widths are computed analytically to one loop order. We discuss the tree level contributions of these new states to the mass spectrum of MSSM sfermions. We also explore production cross sections and decay signatures at colliders for several chosen benchmarks. We find that large regions of parameter space are unconstrained by present collider data.
