Anomaly调解从兰德尔-桑德拉姆到Dine-Seiberg

Anomaly Mediation from Randall-Sundrum to Dine-Seiberg

David Sanford, Yuri Shirman

摘要:

本文重新考虑反常介导的超对称破缺的推导。我们工作在一个一般的形式主义的F-项的共形补偿超场是任意的。这允许在原始推导和最近的异常调解的Dine-Seiberg推导之间进行连续插值。我们表明,物理软参数是独立的补偿F-项和两种形式的结果同意。最后,我们讨论了超对称和非超对称阈值在有效低能拉格朗日量中的作用,以及显式小质量参数(如μ项)对超伴子谱的影响。

英文摘要:

In this paper we reconsider the derivation of anomaly mediated supersymmetry breaking. We work in a general formalism where the F-term of the conformal compensator superfield is arbitrary. This allows for a continuous interpolation between the original derivation and a more recent Dine-Seiberg derivation of anomaly mediation. We show that the physical soft parameters are independent of the compensator F-term and results of two formalisms agree. Finally, we discuss the role of supersymmetric and non-supersymmetric thresholds in the effective low energy Lagrangian as well as the effects of explicit small mass parameters (such as mu-term) on the superpartner spectrum.
