Study of Triple-Gauge-Boson Couplings ZZZ, ZZ$\gamma$ and Z$\gamma\gamma$ at LEP / DELPHI Collaboration
Neutral triple-gauge-boson couplings ZZZ, ZZgam and Zgamgam have been studied with the DELPHI detector using data at energies between 183 and 208 GeV. Limits are derived on these couplings from an analysis of the reactions e+e- -> Zgam, using data from the final states gamma f fbar, with f = q or neutrino, from e+e- -> ZZ, using data from the four-fermion final states q qbar q qbar, q qbar mu+ mu-, q qbar e+ e-, q qbar nu nubar, mu+ mu- nu nubar and e+ e- nu nubar, and from e+e- -> Zgam*, in which the final state gamma is off mass-shell, using data from the four-fermion final states q qbar e+ e- and q qbar mu+ mu-.

$Z\gamma*$ production in $e^+ e^-$ interactions at $\sqrt{s}$ = 183 - 209 GeV / DELPHI Collaboration
Measurements of Zgamma* 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 qbar, mu+ mu- q qbar, q qbar nu nubar), fully leptonic (l+ l- l'+ l'-) and fully hadronic final states (q qbar q qbar, with a low mass q qbar pair).

Measurement and Interpretation of Fermion-Pair Production at LEP energies above the Zo Resonance / DELPHI Collaboration
This paper presents DELPHI measurements and interpretations of cross-sections, forward-backward asymmetries, and angular distributions, for the e+e- -> ffbar process for centre-of-mass energies above the Z resonance, from sqrt(s) ~ 130 - 207 GeV at the LEP collider. The measurements are consistent with the predictions of the Standard Model and are used to study a variety of models including the S-Matrix ansatz for e+e- -> ffbar scattering and several models which include physics beyond the Standard Model: the exchange of Z' bosons, contact interactions between fermions, the exchange of gravitons in large extra dimensions and the exchange of sneutrino in R-parity violating supersymmetry..

Single Intermediate Vector Boson Production in $e^+ e^-$ collisions at $\sqrt{s}$ = 183 and 189 GeV / DELPHI Collaboration
The cross-sections for the production of single charged and neutral intermediate vector bosons were measured using integrated luminosities of 52~pb$^{-1}$ and 154~pb$^{-1}$ collected by the DELPHI experiment at centre-of-mass energies of 182.6~GeV and 188.6~GeV, respectively. The cross-sections for the reactions were determined in limited kinematic regions. [...]

Measurement of the W-pair Production Cross-section and W Branching Ratios in $e^+ e^-$ Collisions at $\sqrt{s}$ = 161-209 GeV / DELPHI Collaboration
These final results on e+e- -> W+W- production cross-section measurements at LEP2 use data collected by the DELPHI detector at centre-of-mass energies up to 209 GeV. Measurements of total cross-sections, W angular differential distributions and decay branching fractions, and the value of the CKM element |V_{cs}| are compared to the expectations of the Standard Model.

A determination of the centre-of-mass energy at LEP2 using radiative two-fermion events / DELPHI Collaboration
Using e+e- -> mu+mu-(gamma) and e+e- -> qqbar(gamma) events radiative to the Z pole, DELPHI has determined the centre-of-mass energy, sqrt{s}, using energy and momentum constraint methods. The results are expressed as deviations from the nominal LEP centre-of-mass energy, measured using other techniques. [...]
