在最小异常介导的超对称破缺模型中，通过引入类似于最小超重力中引入的普通标量质量来避免速子睡眠。这可能会导致非最小的违反味道的相互作用，例如，在方克部门。在本文中，我们根据最新的低能观测值和LHC搜索限制，分析了可行的异常中介超对称破缺参数空间，完成了我们在强子对撞机上与胶子产生相关的破缺超对称粒子产生的分析计算，并研究了LHC异常中介超对称破缺场景下非最小味缺的现象学后果。有关的宇宙学方面也作了简要的讨论。
In minimal anomaly-mediated supersymmetry breaking models, tachyonic sleptons are avoided by introducing a common scalar mass similar to the one introduced in minimal supergravity. This may lead to non-minimal flavour-violating interactions, e.g., in the squark sector. In this paper, we analyze the viable anomaly-mediated supersymmetry breaking parameter space in the light of the latest limits on low-energy observables and LHC searches, complete our analytical calculations of flavour-violating supersymmetric particle production at hadron colliders with those related to gluino production, and study the phenomenological consequences of non-minimal flavour violation in anomaly-mediated supersymmetry breaking scenarios at the LHC. Related cosmological aspects are also briefly discussed.
