在偏折幻影中的暗物质前景

Dark Matter Prospects in Deflected Mirage Mediation

Michael Holmes, Brent D. Nelson

摘要:

最近推出的偏转海市蜃楼调解(DMM)模型是一个字符串驱动的范式,其中所有三个主要的超自然破坏传输机制是可操作的。我们开始系统地探索这个丰富的模型背景下的参数空间,特别注意的高吉诺群众出现的模式。在这项工作中,我们专注于暗物质现象的DMM模型,因为这样的信号是受模型依赖的标量质量的影响最小。我们发现,大部分的参数空间中的三个调解机制有一个类似的有效质量尺度为1 TeV或更少的将探讨未来的直接和间接检测实验。区分偏离海市蜃楼调解没有规范调解的海市蜃楼模型将被证明是困难的,没有对撞机输入,虽然我们表明伽马射线信号可能提供了一个机会,区分这两种范式。

英文摘要:

The recently introduced deflected mirage mediation (DMM) model is a string-motivated paradigm in which all three of the major supersymmetry-breaking transmission mechanisms are operative. We begin a systematic exploration of the parameter space of this rich model context, paying special attention to the pattern of gaugino masses which arise. In this work we focus on the dark matter phenomenology of the DMM model as such signals are the least influenced by the model-dependent scalar masses. We find that a large portion of the parameter space in which the three mediation mechanisms have a similar effective mass scale of 1 TeV or less will be probed by future direct and indirect detection experiments. Distinguishing deflected mirage mediation from the mirage model without gauge mediation will prove difficult without collider input, though we indicate how gamma ray signals may provide an opportunity for distinguishing between the two paradigms.
