夸克-强子跃迁中强子畴的成核

On the nucleation of hadronic domains in the quark-hadron transition

B. W. Mintz, A. Bessa, E. S. Fraga

摘要:

本文给出了在不同膨胀情况下弱一级夸克-强子相变的泡形、成核率和时间演化的数值结果。我们确认了宇宙学一级相变的标准图片,其中的相变是完全由成核。我们还表明,即使膨胀率远低于预期的重离子碰撞成核是非常不可能的,表明主要的相转换机制是调幅分解。

英文摘要:

We present numerical results on bubble profiles, nucleation rates and time evolution for a weakly first-order quark-hadron phase transition in different expansion scenarios. We confirm the standard picture of a cosmological first-order phase transition, in which the phase transition is entirely dominated by nucleation. We also show that, even for expansion rates much lower than those expected in heavy-ion collisions nucleation is very unlikely, indicating that the main phase conversion mechanism is spinodal decomposition.
