Precision electroweak measurements on the $Z$ resonance / ALEPH Collaboration
We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLD experiment using a polarised beam at SLC. [...]

Cross-Sections and Leptonic Forward-Backward Asymmetries from the $Z^0$ Running of LEP / DELPHI Collaboration
During 1993 and 1995 LEP was run at 3 energies near the Z$^0$ peak in order to give improved measurements of the mass and width of the resonance. During 1994, LEP operated only at the Z$^0$peak. [...]

A search for $\eta'_c$ production in photon-photon fusion at LEP / DELPHI Collaboration
A search for the production of the $\eta'_c$ meson, the first radial excitation of the ground state of charmonium $\eta_c$(2980), in the photon-photon fusion reaction at LEP has been performed using the data collected by the DELPHI detector during 1992-1996. No evidence of $\eta'_c$ production is found in the mass region 3520--3800 MeV/c$^2$ [...]

Search for Pair-Produced Neutralinos in Events with Photons and Missing Energy from $e^{+}e^{-}$ Collisions at $\Sqrt{s}=130-183$ GeV / DELPHI Collaboration
The events with two photons and missing (transverse) energy collected by the DELPHI detector at centre-of-mass energies between 130~GeV and 183~GeV have been studied to search for processes of the type $\mbox{e}^+\mbox{e}^- \to \mbox{Y} \mbox{Y}$ with the subsequent decay $\mbox{Y} \to \mbox{X} \gamma$, where X is an undetectable neutral particle. Reactions of this kind are expected in supersymmetric models, where the Y particle can be either the lightest neutralino, decaying to a photon and a gravitino, or the next-to-lightest neutralino, decaying to a photon and the lightest neutralino.

Two-particle angular correlations in $e^+ e^-$ interactions compared with QCD predictions / DELPHI Collaboration
Two--particle angular correlations in jet cones have been measured in $e^+e^-$ annihilation into hadrons at LEP energies ($\sqrt{s}=$ 91 and 183~GeV) and are compared with QCD predictions using the LPHD hypothesis. Two different functions have been tested. [...]

Search for scalar fermions and long-lived scalar leptons at centre-of-mass energies of 130 GeV to 172 GeV / DELPHI Collaboration
Data taken by DELPHI during the 1995 and 1996 LEP runs have been used to search for the supersymmetric partners of electron, muon and tau leptons and of top and bottom quarks. The observations are in agreement with standard model predictions. [...]

Measurement of |V_{cs}| using W decays at LEP2 / DELPHI Collaboration
Decays of $W^{\pm}$ bosons, produced at LEP2, have been used to measure the $|V_{cs}|$ element of the Cabibbo-Kobayashi-Maskawa matrix. Values for $|V_{cs}|$ were extracted both from the measured hadronic branching ratio of $W^{\pm}$ decays and by tagging the flavour of hadronic jets produced in $W^{\pm}$ decays. [...]

The DELPHI experiment at LEP uses Ring Imaging Cherenkov detectors for particle identification. The good understanding of the RICH detectors allows the identification of charged pions, kaons and p rotons, covering the full momentum range from \mbox{$0.7\!<\!p\!<\! 45.6~\gevc$}. [...]

Measurement of the $e^+ e^- \to \gamma\gamma (\gamma)$ cross section at the LEP energies / DELPHI Collaboration
The total and the differential cross-sections for the reaction $e^+e^-\rightarrow \gamma\gamma(\gamma)$ have been measured with the DELPHI detector at LEP % with at centre-of-mass energies from 1 30 %, 136, 161, 172 and to 183 GeV for an integrated luminosity of 78.19.~pb$^{-1}$. %CR An agreement with the QED predictions was found and consequently The results agree with the QED prediction s.
