论文摘要
我们开发了新的扰动工具来准确研究辐射诱导的一阶相变。以前的扰动方法遭受了内部不一致之处，并且在重现晶格数据方面没有成功，这通常归因于无质量模式的红外差异（林德问题）。我们采用一致的功率计数方案来执行计算，并将我们的结果与晶格数据进行比较。我们得出的结论是，一致的扩展消除了许多以前的问题，并表明臭名昭著的林德问题并不像以前认为的那样大的一个因素。
We develop new perturbative tools to accurately study radiatively-induced first-order phase transitions. Previous perturbative methods have suffered internal inconsistencies and been unsuccessful in reproducing lattice data, which is often attributed to infrared divergences of massless modes (the Linde problem). We employ a consistent power counting scheme to perform calculations, and compare our results against lattice data. We conclude that the consistent expansion removes many previous issues, and indicates that the infamous Linde problem is not as big a factor in these calculations as previously thought.
