Limits on [ital Z]-photon couplings from [ital p]-[bar p] interactions at [radical][ital s]=1. 8TeV

We report limits on anomalous [ital ZZ][gamma] and [ital Z][gamma][gamma] couplings derived from an analysis of [ital Z]+photon production based upon approximately 20pb[sup [minus]1] of the [bar p] collision data recorded by the Collider Detector at Fermilab. We observe good agreement with the stand...

Beschreibung
Zusammenfassung:	We report limits on anomalous [ital ZZ][gamma] and [ital Z][gamma][gamma] couplings derived from an analysis of [ital Z]+photon production based upon approximately 20pb[sup [minus]1] of the [bar p] collision data recorded by the Collider Detector at Fermilab. We observe good agreement with the standard model expectation that all [ital Z][gamma] couplings are zero. Confidence level intervals for individual couplings and contours for pairs of [ital CP]-conserving/violating [ital ZZ][gamma] and [ital Z][gamma][gamma] couplings are presented.
