论文摘要
对于宇宙学的一阶电子相变，不需要Baryon数量违反过程的Sphaleron冲洗会导致过渡强度的下限。如果由于颗粒的等离子体而引起的摩擦不足以阻止壁的加速度，则相之间边界的速度，即所谓的气泡壁，可能会成为超偏好的。如果需要由于过渡而导致成功的重子不对称产生，则不应发生这种气泡``失控''。在具有真实规格的标量线场的标准粒子物理模型扩展的背景下，使用Boedeker-Moore标准进行气泡壁失控，我们表明，非失控的过渡要求在一阶相变的强度上具有上限。
For a cosmological first-order electroweak phase transition, requiring no sphaleron washout of baryon number violating processes leads to a lower bound on the strength of the transition. The velocity of the boundary between the phases, the so-called bubble wall, can become ultra-relativistic if the friction due to the plasma of particles is not sufficient to retard the wall's acceleration. This bubble ``runaway'' should not occur if a successful baryon asymmetry generation due to the transition is required. Using Boedeker-Moore criterion for bubble wall runaway, within the context of an extension of the standard model of particle physics with a real gauge-single scalar field, we show that a non runaway transition requirement puts an upper bound on the strength of the first-order phase transition.
