Probing the Scale of New Physics in the $ZZ\gamma$ Coupling at $e^+e^-$ Colliders
The $ZZ\gamma$ triple neutral gauge couplings are absent in the Standard Model (SM) at the tree level. They receive no contributions from dimension-6 effective operators, but can arise from effective operators of dimension-8. We study the scale of new physics associated with such dimension-8 operato...
