超对称暗扇区中的暗物质

Dark Matter in Very Supersymmetric Dark Sectors

Avital Dery, Jeff A. Dror, Laurel Stephenson Haskins, Yonit Hochberg, Eric Kuflik

摘要:

如果超对称性在任何尺度下都存在,不管它是否在弱尺度附近恢复,它都可能是暗区的一个很好的对称性,在其最低的费米子和玻色子之间强制简并。我们探讨这种情况下的早期宇宙和暗物质的影响,以及相应的签名。特别是,我们表明,在大部分的参数空间的共同衰变的暗物质的暗部门的热历史的结果。这意味着新的唯象签名,并提出了一种新的方法来发现高尺度超对称性。

英文摘要:

If supersymmetry exists at any scale, regardless of whether it is restored around the weak scale, it may be a good symmetry of the dark sector, enforcing a degeneracy between its lowest lying fermions and bosons. We explore the implications of this scenario for the early universe and dark matter, as well as the corresponding signatures. In particular we show that the thermal history of the dark sector results in co-decaying dark matter in much of the parameter space. This implies new phenomenological signatures and presents a new way to discover high scale supersymmetry.
