SuperGUT统一模型中的暗物质

Dark Matter in SuperGUT Unification Models

Keith A. Olive

摘要:

在简要介绍了约束版本的MSSM(CMSSM)中暗物质的前景及其与基于最小超引力(mSUGRA)的模型的差异之后,我将考虑在M_{GUT}以上的尺度上统一超引力破坏参数的影响。superGUT统一的后果之一,是能够采取消失的标量质量在统一尺度与中性伴子LSP暗物质候选人。这使得人们可以复活无尺度超引力作为一个可行的唯象模型。

英文摘要:

After a brief update on the prospects for dark matter in the constrained version of the MSSM (CMSSM) and its differences with models based on minimal supergravity (mSUGRA), I will consider the effects of unifying the supersymmetry-breaking parameters at a scale above M_{GUT}. One of the consequences of superGUT unification, is the ability to take vanishing scalar masses at the unification scale with a neutralino LSP dark matter candidate. This allows one to resurrect no-scale supergravity as a viable phenomenological model.
