中性混合反常$U(1)'$模型中的暗物质

Dark Matter in Anomalous $U(1)'$ Models with neutral mixing

Francesco Fucito, Andrea Lionetto, Andrea Mammarella

摘要:

我们研究了由膜结构启发的最小超对称标准模型的反常$U(1)'$扩展的费米子扇区中的最轻质量。这个模型的LSP是一个XWIMP(极弱相互作用粒子),它被证明有一个遗迹密度满足WMAP数据。在将DarkSUSY软件包适应我们的情况后,进行了数值计算。

英文摘要:

We study the lightest masses in the fermionic sector of an anomalous $U(1)'$ extension of the minimal supersymmetric standard model inspired by brane constructions. The LSP of this model is an XWIMP (extremely weak interaction particle) which is shown to have a relic density satisfying WMAP data. This computation is carried out numerically after having adapted the DarkSUSY package to our case.
