在一类规范-希格斯统一模型中，作为规范场额外维分量的4D中性希格斯玻色子由于规范不变性和动态产生的新宇称而变得绝对稳定，成为冷暗物质（CDM）的一个有希望的候选者。我们证明了在SO（5）×U（1）模型中，在Higgs质量约为70 GeV的扭曲空间中，观测到的冷暗物质的残余丰度是得到的。希格斯-核子散射截面被发现是接近目前的CDMS II和XENON 10的直接探测暗物质的边界。
In a class of the gauge–Higgs unification models the 4D neutral Higgs boson, which is a part of the extra-dimensional component of the gauge fields, becomes absolutely stable as a consequence of the gauge invariance and dynamically generated new parity, serving as a promising candidate for cold dark matter (CDM). We show that the observed relic abundance of cold dark matter is obtained in the SO(5)×U(1) model in the warped space with the Higgs mass around 70 GeV. The Higgs–nucleon scattering cross section is found to be close to the current CDMS II and XENON10 bounds in the direct detection of dark matter.
