异常四次规范耦合的因果约束与分析约束

Causal vs. Analytic constraints on anomalous quartic gauge couplings

Luca Vecchi

摘要:

利用两个纵向极化矢量玻色子的弹性散射振幅的一般非前向色散关系,导出了反常四次规范耦合的单圈约束。我们比较了这个结果与另一个假设的基础理论满足因果关系原则的狭义相对论,并表明,后者是更多的约束。

英文摘要:

We derive one loop constraints on the anomalous quartic gauge couplings using a general non-forward dispersion relation for the elastic scattering amplitude of two longitudinally polarized vector bosons. We compare this result with another one derived by the assumption that the underlying theory satisfies the causality principle of Special Relativity and show that this latter is more constraining.
