利用两个纵向极化矢量玻色子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。我们表明，确切的手征理论更严格的界限，可以得到的假设基础理论满足狭义相对论的因果关系原理。
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 show that for exactly chiral theories more stringent bounds can be obtained by the assumption that the underlying theory satisfies the causality principle of Special Relativity.
