论文摘要
我们引入了一种新的Higgs自然性问题的方法，其中Higgs质量的价值与宇宙稳定性和大型可观察宇宙的可能性相关。希格斯与CFT部门的Dilaton混合，其真正的基态具有较大的负真空能。如果Higgs VEV不零，低于$ \ Mathcal {o}（{\ rm tev}）$，则CFT还接受了第二个稳定的真空，其中宇宙的扩展历史是常规的。结果，只有Higgs质量值不自然值的Hubble斑块支持通货膨胀和通货膨胀后的扩张，而所有其他斑块都会迅速紧缩。驱动Dilaton潜力的基本希格斯vev是我们对层次结构问题的新解决方案的本质。主要的实验预测是在0.1-10 GEV范围内的光diLATON场，与Higgs混合。一部分可行的参数空间已经通过稀有B-膜衰减的测量进行了探测，其余的将通过未来的山脉和搜索光，弱耦合粒子的实验充分探索。
We introduce a new approach to the Higgs naturalness problem, where the value of the Higgs mass is tied to cosmic stability and the possibility of a large observable Universe. The Higgs mixes with the dilaton of a CFT sector whose true ground state has a large negative vacuum energy. If the Higgs VEV is non-zero and below $\mathcal{O}({\rm TeV})$, the CFT also admits a second metastable vacuum, where the expansion history of the Universe is conventional. As a result, only Hubble patches with unnaturally small values of the Higgs mass support inflation and post-inflationary expansion, while all other patches rapidly crunch. The elementary Higgs VEV driving the dilaton potential is the essence of our new solution to the hierarchy problem. The main experimental prediction is a light dilaton field in the 0.1-10 GeV range that mixes with the Higgs. Part of the viable parameter space has already been probed by measurements of rare B-meson decays, and the rest will be fully explored by future colliders and experiments searching for light, weakly-coupled particles.
