摘要:

受电弱希格斯真空稳定性的驱动,我们考虑标准模型可能一直有效到约 10^{10} GeV 至接近普朗克尺度的大尺度范围。一个合理的图景是涌现标准模型:规范对称性源于紫外深处某种类拓扑相变。在这种情况下,宇宙学常数尺度与中微子质量应具有相近的大小,并被大涌现尺度因子所压低。其关键物理涉及庞加莱不变性、质量产生与重整化群不变性之间微妙的相互作用。希格斯质量将在与真空稳定性相关的环境中被选择。本文还讨论了其对暗物质模型的影响。

英文摘要:

Motivated by the stability of the electroweak Higgs vacuum we consider the possibility that the Standard Model might work up to large scales between about $10^{10}$ GeV and close to the Planck scale. A plausible scenario is an emergent Standard Model with gauge symmetries originating in some topological like phase transition deep in the ultraviolet. In this case the cosmological constant scale and neutrino masses should be of similar size, suppressed by factor of the large scale of emergence. The key physics involves a subtle interplay of Poincaré invariance, mass generation and renormalisation group invariance. The Higgs mass would be environmentally selected in connection with vacuum stability. Consequences for dark matter scenarios are discussed.
