采用规范不变方法的一阶电弱相变

First-order Electroweak phase transition with Gauge-invariant approach

Renhui Qin, Ligong Bian

AI总结:

本研究采用规范不变方法结合三维标准模型有效场论研究电弱相变,发现两圈阶相变参数与维数约化方法偏差在百分比量级,且590 GeV以上新物理标度的引力波信号无法被现有空间干涉仪探测。

摘要:

我们借助三维标准模型有效场论,通过规范不变方法研究电弱相变动力学。我们发现,在两圈阶,用规范不变方法得到的相变参数与维数约化方法得到的结果相比,最大偏差约为百分比量级。我们进一步发现,在新物理标度$Λ\gtrsim 590$ GeV下预测的引力波信号,无法被LISA、TianQin、Taiji等空间干涉仪探测到。

英文摘要:

We study the electroweak phase transition dynamics with a three-dimensional standard model effective field theory under a gauge-invariant approach. We observe that, at the two-loop level, the phase transition parameters obtained with the gauge invariant approach can at most deviate from that of the dimensional reduction method around the percent level. We further found that the predicted gravitational wave signals at the new physics scale $Λ\gtrsim 590$ GeV are unreachable by the space-based interferometers, such as: LISA, TianQin, and Taiji.
