Limits on the Masses of Supersymmetric Particles at $\sqrt{s}$=189 GeV / DELPHI Collaboration
Searches for charginos, neutralinos and sleptons at LEP2 centre-of-mass energies from 130 GeV to 189 GeV have been used to set lower limits on the mass of the Lightest Supersymmetric Particle and other supersymmetric particles within the MSSM framework. R-parity conservation has been assumed. [...]

Search for scalar top and scalar bottom quarks at $\sqrt {s} $ = 183 GeV at LEP / OPAL Collaboration
Searches for a scalar top quark and a scalar bottom quark have been performed using a total data sample of 56.8 pb-1 at a centre-of-mass energy of 183 GeV collected with the OPAL detector at LEP. No candidate events were observed. [...]

Searches for supersymmetric particles in $e^{+} e^{-}$ collisions up to 208 GeV and interpretation of the results within the MSSM / DELPHI Collaboration
DELPHI data collected at centre-of-mass energies up to 208 GeV have been analysed to search for charginos, neutralinos and sfermions in the framework of the Minimal Supersymmetric Standard Model (MSSM) with R-parity conservation. No evidence for a signal was found in any of the channels. [...]

Update of the search for charginos nearly mass-degenerate with the lightest neutralino / DELPHI Collaboration
The data collected by DELPHI in 1998 at the centre-of-mass energy of 189~GeVhave been used to update the search for charginos nearly mass-degenerate withthe lightest supersymmetric particle, which is assumed to be the lightest neutralino. Mass differences below $\Delta M\!=\!3$~GeV/c$^2$ are considered.No excess of events with respect to the Standard Model expectation has beenobserved, and exclusions in the plane of $\Delta M$ versus chargino mass are given.

Update of the search for supersymmetric particles in scenarios with Gravitino LSP and Sleptons NLSP / DELPHI Collaboration
An update of the search for sleptons, neutralinos and charginos in the context of scenarios where the lightest supersymmetric particle is the gravitino and the next-to-lightest supersymmetric particle is a slepton, is presented, together with the update of the search for heavy stable charged particles in light gravitino scenarios and Minimal Supersymmetric Standard Models. Data collected in 1999 with the DELPHI detector at centre-of-mass energies around 192, 196, 200 and 202 GeV were analysed. [...]

Search for SUSY in the AMSB scenario with the DELPHI detector / DELPHI Collaboration
The DELPHI experiment at the LEP e+e- collider collected almost 700 pb^-1 at centre-of-mass energies above the Z0 mass pole and up to 208 GeV. Those data were used to search for SUSY in the Anomaly Mediated SUSY Breaking (AMSB) scenario with a flavour independent common sfermion mass parameter. [...]

Search for R-parity Violating Decays of Supersymmetric Particles in $e^+ e^-$ Collisions at LEP / L3 Collaboration
A search, in $e^+ e^-$ collisions, for chargino, neutralino, scalar lepton and scalar quark pair-production is performed, without assuming R-parity conservation in decays, in the case that only one of the coupling constants $\lambda_{ijk}$ or $\lambda''_{ ijk}$ is non-negligible. No signal is found in data up to a centre-of-mass energy of 208 \GeV. [...]

Search for neutralino pair production at $\sqrt{s}$ = 189 GeV / DELPHI Collaboration
A search for pair-production of neutralinos at a LEP centre-of-mass energy of 189 GeV gave no evidence for a signal. This limits the neutralino production cross-section and excludes regions in the parameter space of the Minimal Supersymmetric Standard Model (MSSM)..

Search for Chargino and Neutralino Production at $\sqrt{s} = 189 GeV$ at LEP / OPAL Collaboration
A search for charginos and neutralinos, predicted by supersymmetric theories, is performed using a data sample of 182.1 pb-1 taken at a centre-of-mass energy of 189 GeV with the OPAL detector at LEP. No evidence for chargino or neutralino production is found. [...]

Final results from DELPHI on the searches for SM and MSSM Neutral Higgs bosons / DELPHI Collaboration
These final results from DELPHI searches for the Standard Model (SM) Higgs boson, together with benchmark scans of the Minimal Supersymmetric Standard Model (MSSM) neutral Higgs bosons, used data taken at centre-of-mass energies between 200 and 209 GeV with a total integrated luminosity of 224 pb^-1. The data from 192 to 202 GeV are reanalysed with improved b-tagging for MSSM final states decaying to four b-quarks. [...]
