在Randall-Sundrum扭曲时空中，四维希格斯场与规范场统一，电弱对称被细谷机制动态破缺的动态规范-希格斯统一中，计算了WWZ、WWH和ZZH的三线性耦合，其中H代表希格斯场。后两种耦合被额外维度中Yang-Mills Aharonov-Bohm相位的cost θ h θ因子抑制，而WWZ耦合保持与标准模型相同，精度较高。
In the dynamical gauge–Higgs unification in the Randall–Sundrum warped spacetime, where the 4D Higgs field is unified with gauge fields and the electroweak symmetry is dynamically broken by the Hosotani mechanism, the trilinear couplings for WWZ, WWH, and ZZH, where H stands for the Higgs field, are evaluated. The latter two couplings are suppressed by a factor of cosθHwhere θHis the Yang–Mills Aharonov–Bohm phase in the extra dimension, while the WWZ couplings remain the same as in the standard model to good accuracy.
