AbstractMeasurements of Zγ* production are presented using data collected by the DELPHI detector at centre-of-mass energies ranging from 183 to 209 GeV, corresponding to an integrated luminosity of about 667 pb(-1). The measurements cover a wide range of the possible final state four-fermion configurations: hadronic and leptonic (e(+)e(-)q(q)over-bar, μ(+)μ(-)q(q)over-bar, q(q)over-bar v(v)over-bar), fully leptonic (l(+)l(-)l'(+)l'-)) and fully hadronic final states (q(q)over-bar q(q)over-bar, with a low mass q(q)over-bar pair). Measurements of the Zγ* cross-section for the various final states have been compared with the Standard Model expectations and found to be consistent within the errors. In addition, a total cross-section measurement of the l(+)l(-)l'(+)l'(-) cross-section is reported, and found to be in agreement with the prediction of the Standard Model.
