Zγ* production in e+e- √s = 183-209 GeV

Journal article

Measurements 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-qq, μ+μ-qq̄, qqνν), fully leptonic (l +l-l'+l'-) and fully hadronic final states (qq̄, qq̄, with a low mass qq̄ 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. © 2007 Springer-Verlag / Società Italiana di Fisica.
