论文摘要
我们考虑了一种场景，在通货膨胀期间，通过松弛机制稳定了电动量表，重点是通过限制新的强烈相互作用的矢量样费米（Fermions）产生后反应电位的情况。如果加热温度足够高以引起新的强相互作用的解密，则后反应屏障会消失，并且宇宙经历了第二个松弛阶段。当温度足够下降以使后反应再次形成时，此阶段停止。我们确定了第二张弛豫阶段不会破坏电子量表的成功稳定的参数空间区域。另外，第二次弛豫阶段结束的后反应电位的产生可能与强大的一级相变相关。然后，我们研究这种过渡何时可以在未来干涉仪实验的可检测性范围内产生重力波信号。
We consider a scenario in which the electroweak scale is stabilized via the relaxion mechanism during inflation, focussing on the case in which the back-reaction potential is generated by the confinement of new strongly interacting vector-like fermions. If the reheating temperature is sufficiently high to cause the deconfinement of the new strong interactions, the back-reaction barrier then disappears and the Universe undergoes a second relaxation phase. This phase stops when the temperature drops sufficiently for the back-reaction to form again. We identify the regions of parameter space in which the second relaxation phase does not spoil the successful stabilization of the electroweak scale. In addition, the generation of the back-reaction potential that ends the second relaxation phase can be associated to a strong first order phase transition. We then study when such transition can generate a gravitational wave signal in the range of detectability of future interferometer experiments.
