A basis of dimension-eight operators for anomalous neutral triple gauge boson interactions
arXiv:1308.6323 · doi:10.1007/JHEP02(2014)101
Abstract
Four independent dimension-eight operators give rise to anomalous neutral triple gauge boson interactions, one CP-even and three CP-odd. Only the CP-even operator interferes with the Standard Model for the production of a pair of on-shell neutral bosons. However, the effects are found to be tiny due mainly to the mismatch of the Z boson polarization between the productions from the SM and the new operator.
