论文摘要
我们考虑标准模型HIGGS标量扇区的比例对称扩展。新的部门Dilaton负责产生质量量表，并且可能在Weyl Gravity $ \ tilde {R}^2 $ enmer中具有几何起源。我们展示了温度作为质量量表如何明确和通过不变的热VEV明确打破对称性的对称性。此外，我们证明了Dilaton-Higgs系统的宇宙学演化可以导致较晚的时间质量尺度，这与标准模型一致。
We consider a scale symmetric extension of the Standard Model Higgs scalar sector. The new sector, dilaton, is responsible for the generation of mass scales and may have geometric origin in the Weyl gravity $\tilde{R}^2$ term. We show how temperature as a mass scale breaks scale symmetry explicitly and through a nonvanishing thermal vev. In addition we demonstrate that cosmological evolution of the dilaton-Higgs system can lead to late time mass scales, which agree with the Standard Model.
