论文摘要
人们普遍认为，应在具有快速移动的气泡壁的强相变过的强相变过中抑制电动eakeogenogeny，但是从未对这种效果进行定量研究。我们重新循环流体方程，描述了气泡壁附近粒子不对称的运输，而无需进行小壁效率近似。我们表明，抑制baryon不对称是壁速的平稳函数，并且在越过声速屏障时没有特殊的行为。因此，通过强烈的爆炸也可以有效地有效地与具有大量重力波的模型相关。我们还基于VEV插入形式主义，将改进的传输方程式与文献中通常使用的另一个通常使用的传输方程进行系统和批判性比较。
It is widely believed that electroweak baryogenesis should be suppressed in strong phase transitions with fast-moving bubble walls, but this effect has never been quantitatively studied. We rederive fluid equations describing transport of particle asymmetries near the bubble wall without making the small-wall-velocity approximation. We show that the suppression of the baryon asymmetry is a smooth function of the wall speed and that there is no special behavior when crossing the sound speed barrier. Electroweak baryogenesis can thus be efficient also with strong detonations, generically associated with models with observably large gravitational waves. We also make a systematic and critical comparison of our improved transport equations to another one commonly used in the literature, based on the VEV-insertion formalism.
