遗迹密度和未来对撞机:逆问题

Relic density and future colliders: inverse problem(s)

A. Arbey, F. Mahmoudi

摘要:

遗迹密度计算经常被用来约束粒子物理模型,特别是超对称性。我们将证明,在大爆炸核合成之前,额外的能量或熵的存在可以完全改变超对称参数空间上的残余密度约束。因此,当使用遗迹密度来约束超对称性时,应该非常小心,因为它可能会产生误导性的结果,特别是如果与未来的对撞机数据相结合。或者,我们还将表明,结合未来对撞机的发现与遗迹密度计算可以揭示无法访问的前BBN暗时物理。最后,我们将介绍SuperIso Relic,一个新的超对称遗迹密度计算器代码,它包含了其他宇宙学模型,并且是公开的。

英文摘要:

Relic density calculations are often used to constrain particle physics models, and in particular supersymmetry. We will show that the presence of additional energy or entropy before the Big-Bang nucleosynthesis can however completely change the relic density constraints on the SUSY parameter space. Therefore one should be extremely careful when using the relic density to constrain supersymmetry as it could give misleading results, especially if combined with the future collider data. Alternatively, we will also show that combining the discoveries of the future colliders with relic density calculations can shed light on the inaccessible pre-BBN dark time physics. Finally we will present SuperIso Relic, a new relic density calculator code in Supersymmetry, which incorporates alternative cosmological models, and is publicly available.
