电弱弛豫的引力实验

Gravitational tests of electroweak relaxation

Daniele Barducci, Enrico Bertuzzo, Martín Arteaga Tupia

摘要:

我们考虑的情况下,电弱尺度是稳定的,通过在通货膨胀期间的弛豫机制,专注于在这种情况下,其中的反反应势产生的约束新的强相互作用的矢量类费米子。如果再加热温度足够高,导致新的强相互作用解除限制,那么反反应势垒就会消失,宇宙就会经历第二个弛豫阶段。当温度下降到足以再次形成逆反应时,该阶段停止。我们确定的区域参数空间中的第二弛豫阶段不破坏成功的稳定的电弱规模。另外,结束第二弛豫阶段的反反应电势的产生可以与强的一阶相变相关联。然后,我们研究当这样的过渡可以产生一个引力波信号在未来的干涉仪实验的可探测范围。

英文摘要:

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.
