摘要
本文提出了一类新的电弱等级问题的解，它既不需要弱标度动力学，也不需要人择原理。早期宇宙中的动力学演化将希格斯质量驱动至远小于截断的值。最简单的模型具有标准模型的粒子内容加上一个 QCD 轴子和一个暴胀扇区。在任何技术自然模型中达到的最高截断为 10^8 GeV。

备注
10 pages, 2 figures. v2: We describe a way in which the bound on the cutoff in the QCD model can be raised to 1000 TeV. We've added a discussion of constraints on reheating. An additional constraint is noted for the non-QCD model. Other clarifications of the model added throughout
