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. [...]

Study of the four-jet anomaly observed at LEP centre-of-mass energies of 130 and 136 GeV / DELPHI Collaboration
The four-jet events collected by \delphi\ during the speciaLEP run at centre-of-mass energies of 130 and 136 \GeV\ in 1997 with an integrated luminosity of $5.9 \ipb $ are analysed. Their rate and the distributions of their di-jet masses, their smallest jet charges, and their di-jet charge separations alagree welwith Standard Modepredictions. [...]

Measurement of $A_{FB}^{\overline{b}b}$ in Hadronic Z Decays using a Jet Charge Technique / DELPHI Collaboration
The $\BB$ forward-backward asymmetry %, $\AFBbb$, has been determined from the average charge flow %, $\langle Q_{FB}\rangle$, measured in a sample of 3,500,000 hadronic Z decays collected with the DELPHI detector in 1992 - 1995. The measurement is performed in an enriched $\BB$ sample selected using an impact parameter tag and results in the following values for the $\BB$ forward-backward asymmetry: \begin {center} \begin{tabular}{ccl} \AFBbb (89.55 GeV) & = & $0.068\,\ \pm0.018\,\ (\mbox{stat.})\pm0.0013 (\mbox{syst.})$ \\ \AFBbb (91.26 GeV) & = & $0.0982\pm0.0047(\mbox{stat.})\pm0.0016(\mbox{syst.})$ \\ \AFBbb (92.94 GeV) & = & $0.123\,\ \pm0.016\,\ (\mbox{stat.})\pm0.0027(\mbox{ syst.})$ \\ \end{tabular} \end{center} %at an average center of mass energy of 91.251\, GeV [...]

A precise measurement of the partial decay width ratio $R_{b}^{0} = \Gamma_{b\overline{b}}/\Gamma_{had}$ / DELPHI Collaboration
The partial decay width of the Z to $\bb$ quark pairs has beenmeasured by the DELPHI detector at LEP using data taken in the years1992 to 1995.Decays of b-hadrons were tagged by several methods usingtracks with large impact parameters and/or reconstructed secondary vertices, complemented by event shape variables.Combining these methods in a multivariate analysis the value\[\frac{\Gamma({\mathrm Z \rightarrow \bb}) }{ \Gamma({\mathrm {Z \rightarrow had}}) } = 0.21634 \pm 0.00067({\mathrm {stat}}) \pm 0.00060 ({\mathrm {syst}})\]was obtained, where the ${\mathrm c} \bar {\mathrm c}$ production fractionwas fixed to its Standard Model value..

Search for Leptoquarks and FCNC in $e^{+} e^{-}$ annihilations at $\sqrt{s}$=183 GeV / DELPHI Collaboration
A search for events with one jet and at most one isolated lepton used data taken at LEP-2 by the DELPHI detector.These data were accumulated at a center-of-mass energy of 183 GeV and correspond to an integrated luminosity of 47.7 1/pb. Production of single scalar and vector leptoquarks was searched for. [...]

Search for charginos, neutralinos and gravitinos in $e^{+} e^{-}$ interactions at $\sqrt{s}$=183 GeV / DELPHI Collaboration
An update of the searches for charginos and neutralinos is presented, basedon a data sample corresponding to the 53.9 pb$^{-1}$ recorded by the DELPHIdetector in 1997, at a centre-of-mass energy of 183 GeV. No evidence for asignal was found. [...]

A search for heavy stable and long-lived squarks and sleptons in $e^+ e^-$ collisions at energies from 130 to 183 GeV / DELPHI Collaboration
A search for stable and long-lived heavy charged particles used the data taken by the DELPHI experiment at energies from 130 to 183 GeV. The Cherenkov light detected in the Ring Imaging Cherenkov Detector and the ionization loss measured in the Time Projection Chamber identify heavy particles from masses of 2 to nearly 89 GeV/c^2.
