标题： Sphaleron transition rate at high temperature in the 1+1 D abelian Higgs model

摘要： 利用经典近似下的正则系综在空间点阵上，我们得到了这一速率的新结果。 我们发现高温下该速率与 $T^2$成正比，并且强烈依赖于点阵间距 $a$。 我们得出结论：经典近似需要一个更有效的行动（作用量）。 显示英文摘要

摘要： New results for the rate are presented using the canonical ensemble in the classical approximation on a spatial lattice. We find that the rate at high temperatures is proportional to $T^2$, and strongly dependent on the lattice spacing $a$. We conclude that a better effective action is needed for the classical approximation.
