摘要:

我们考虑了经典尺度不变的Higgs-Escherton动力学对称性破缺模型,扩展了一个额外的标量场,发挥了暗物质的作用。希格斯玻色子是在不同对称性破缺相之间的临界边界附近的光,在那里超越通常的吉尔德纳-温伯格近似的量子校正变得相关。这意味着暗物质和希格斯现象学之间有更紧密的联系。该模型只有三个自由参数,但它允许观测到的暗物质遗迹丰度,同时尊重所有的约束。由希格斯玻色子介导的直接探测截面仅由暗物质质量决定,并可在未来的实验中进行测试。

英文摘要:

We consider the classically scale invariant Higgs-dilaton model of dynamical symmetry breaking extended with an extra scalar field that plays the role of dark matter. The Higgs boson is light near a critical boundary between different symmetry breaking phases, where quantum corrections beyond the usual Gildener-Weinberg approximation become relevant. This implies a tighter connection between dark matter and Higgs phenomenology. The model has only three free parameters, yet it allows for the observed relic abundance of dark matter while respecting all constraints. The direct detection cross section mediated by the Higgs boson is determined by the dark matter mass alone and is testable at future experiments.
