论文摘要
宇宙学一阶相变的能量预算对于重力波谱至关重要。以前的大多数研究都是基于在对称和破碎相中具有相同声音速度的袋模型。我们研究了袋模型之外的能量预算和相应的重力波光谱，在对称和破碎的相中，声速度可能有所不同。以Higgs的有效模型为代表模型，我们计算出不同阶段，重力波光谱和信噪比的声音速度，以超出袋模型以外的相变参数的不同组合。我们将这些新结果与从袋模型中获得的结果进行了比较。适当温度下的适当声速和相变参数对于获得更精确的预测很重要。
The energy budget of cosmological first-order phase transition is essential for the gravitational wave spectra. Most of the previous studies are based on the bag model with same sound velocity in the symmetric and broken phase. We study the energy budget and the corresponding gravitational wave spectra beyond the bag model, where the sound velocities could be different in the symmetric and broken phase. Taking the Higgs sextic effective model as a representative model, we calculate the sound velocities in different phase, the gravitational wave spectra and the signal-to-noise ratio for different combinations of phase transition parameters beyond the bag model. We compare these new results with the ones obtained from the bag model.The proper sound velocities and phase transition parameters at the appropriate temperature are important to obtain more precise predictions.
