稳定的希格斯玻色子-冷暗物质的新候选者-

Stable Higgs Bosons - new candidate for cold dark matter -

Yutaka Hosotani

摘要:

希格斯玻色子是电弱相互作用的标准模型的基础。它必须以某种形式存在,以实现相互作用的统一。在规范-希格斯统一方案中,希格斯玻色子成为规范场的额外维分量的一部分。希格斯玻色子在一类规范-希格斯统一模型中变得绝对稳定,是宇宙中冷暗物质的一个有希望的候选者。观测到的冷暗物质的遗迹丰度是在希格斯粒子质量约为70 GeV时获得的。在对暗物质的直接探测中,发现Higgs-核子散射截面与最近的CDMS II和XENON 10边界接近。在对撞机实验中,稳定的希格斯玻色子玻色子是成对产生的,以丢失的能量和动量出现,因此探测希格斯玻色子玻色子的方法必须改变。

英文摘要:

The Higgs boson is in the backbone of the standard model of electroweak interactions. It must exist in some form for achieving unification of interactions. In the gauge-Higgs unification scenario the Higgs boson becomes a part of the extra-dimensional component of gauge fields. The Higgs boson becomes absolutely stable in a class of the gauge-Higgs unification models, serving as a promising candidate for cold dark matter in the universe. The observed relic abundance of cold dark matter is obtained with the Higgs mass around 70 GeV. The Higgs-nucleon scattering cross section is found to be close to the recent CDMS II and XENON10 bounds in the direct detection of dark matter. In collider experiments stable Higgs bosons are produced in a pair, appearing as missing energies and momenta so that the way of detecting Higgs bosons must be altered.
