论文摘要

我们考虑在较重的新物理学存在下与希格斯耦合的超光标度。在电动相破裂的相位,希格斯对光量表的电势产生了树级的贡献,而新物理学则在循环水平上贡献。因此,该理论具有宇宙学上稳定的阶段,其中光标量在其潜力的顶部附近,而希格(Higgs)比新物理学更轻。这种自然性不稳定的地区是原始和环保的,因为较重的希格斯迅速紧缩的区域很快。我们预计在状态的黑暗能源方程中滚动的效果可见。此外,可以将真空能量降至弱尺度,从而取消到较小的值。

We consider an ultra-light scalar coupled to the Higgs in the presence of heavier new physics. In the electroweak broken phase the Higgs gives a tree-level contribution to the light-scalar potential, while new physics contributes at loop level. Thereby, the theory has a cosmologically meta-stable phase where the light scalar is around the top of its potential, and the Higgs is a loop factor lighter than new physics. Such regions with precarious naturalness are anthropically and environmentally selected, as regions with heavier Higgs crunch quickly. We expect observable effects of rolling in the dark-energy equation of state. Furthermore, vacuum energies up to the weak scale can be canceled down to anthropically small values.
