规范中介的多样性:动态SUSY断裂的足迹

On the Diversity of Gauge Mediation: Footprints of Dynamical SUSY Breaking

Steven Abel, Joerg Jaeckel, Valentin V. Khoze, Luis Matos

摘要:

最近在实现动力学超对称性破缺方面的进展允许构建简单且可计算的规范中介模型。我们讨论的现象学的特别是最小的情况下,调解是直接的,并表明,有通用的新的和惊人的预测。这些新粒子的质量与标准模型的超伙伴相当,与动力学超对称断裂扇区的伪戈德斯通模式有关。因此,不可避免地要背离MSSM。此外,高吉诺的质量通常比费米子轻得多,并且它们的质量比可以不同于标准规范中介中规范耦合所规定的模式。我们调查这些功能在两个不同的实现的动态超对称性打破部门。

英文摘要:

Recent progress in realising dynamical supersymmetry breaking allows the construction of simple and calculable models of gauge mediation. We discuss the phenomenology of the particularly minimal case in which the mediation is direct, and show that there are generic new and striking predictions. These include new particles with masses comparable to those of the Standard Model superpartners, associated with the pseudo-Goldstone modes of the dynamical SUSY breaking sector. Consequently there is an unavoidable departure from the MSSM. In addition the gaugino masses are typically significantly lighter than the sfermions, and their mass ratios can be different from the pattern dictated by the gauge couplings in standard (i.e. explicit) gauge mediation. We investigate these features in two distinct realisations of the dynamical SUSY breaking sector.
