论文摘要
我们考虑了动态对称性破坏的经典规模不变的希格斯 - 迪拉顿模型，并具有扮演暗物质作用的额外标量场。希格斯玻色子在不同的对称断裂阶段之间的临界边界附近，其中量子校正超出了通常的Gildener-Weinberg近似值。这意味着暗物质与希格斯现象学之间存在更紧密的联系。该模型只有三个自由参数，但是它允许在尊重所有约束的同时观察到的深色物质。 Higgs玻色子介导的直接检测横截面仅由暗物质质量确定，并且可以在将来的实验中进行测试。
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.
