我们对电弱闪片周围的量子涨落进行了分析，并计算了相关的行列式，该行列式对闪片跃迁速率进行了单环校正。该计算在多个技术方面与卡森及其同事之前的分析有所不同，因此可以被视为独立的。数值结果也与之前的分析结果相差几个数量级；我们发现，sphaleron 转变率受到的抑制比以前发现的要少得多。
We present an analysis of the quantum fluctuations around the electroweak sphaleron and calculate the associated determinant which gives the one-loop correction to the sphaleron transition rate. The calculation differs in various technical aspects from a previous analysis by Carson and co-workers so that it can be considered as independent. The numerical results differ also, by several orders of magnitude, from those of this previous analysis; we find that the sphaleron transition rate is much less suppressed than found previously.
