USSM中的中微子暗物质

Neutralino Dark Matter in the USSM

J. Kalinowski, S. F. King, J. P. Roberts

摘要:

本文提供了一个全面的讨论中性伴子暗物质类的扩展超对称模型称为USSM包含一个额外的SM单重态希格斯加上一个额外的$Z'$,连同它们的超伙伴的singlino和bino '。USSM的这些额外状态可以显著地改变中性伴子暗物质相对于最小(甚至接近最小)超对称标准模型的性质和性质。我们推导出费曼规则的USSM和计算的暗物质遗迹丰度和直接探测率的弹性散射在USSM的参数空间的最大差异的有趣的区域,预计。

英文摘要:

This paper provides a comprehensive discussion of neutralino dark matter within classes of extended supersymmetric models referred to as the USSM containing one additional SM singlet Higgs plus an extra $Z'$, together with their superpartners the singlino and bino'. These extra states of the USSM can significantly modify the nature and properties of neutralino dark matter relative to that of the minimal (or even next-to-minimal) supersymmetric standard models. We derive the Feynman rules for the USSM and calculate the dark matter relic abundance and direct detection rates for elastic scattering in the USSM for interesting regions of parameter space where the largest differences are expected.
