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.

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. [...]

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. [...]

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 Spontaneous R-parity violation at $\sqrt{s}$ = 183 GeV and 189 GeV / DELPHI Collaboration
Searches for spontaneous $R$-parity violating signals at $\sqrt{s}=183$\,GeV and \mbox{$\sqrt{s}=189$\,GeV} have been performed using 1997 and 1998 DELPHI data, under the assumption of $R$-parity breaking in the third lepton family. The expected topology for the decay of a pair of charginos into two acoplanar taus plus missing energy was investigated and no evidence for a signal was 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. [...]

Search for Charginos with a Small Mass Difference to the Lightest Supersymmetric Particle at $\sqrt{s} = 189 GeV$ / L3 collaboration
A search for charginos nearly mass-degenerate with the lightestsupersymmetric particle isperformed using the 176 {pb$^{-1}$ of data collected at 189 {Ge\kern -0.1em V} in 1998 with the L3detector. Mass differences between the chargino and the lightest supersymmetric particlebelow 4 {Ge\kern -0.1em V} are considered.The presence of a high transverse momentum photon is required to single out the signal from the photon-photon interaction background.

Search for supersymmetric particles in light gravitino scenarios and sleptons NLSP / DELPHI Collaboration
A search for sleptons, neutralinos, charginos, sgoldstinos and heavy stable charged sleptons in the context of scenarios where the lightest supersymmetric particle is the gravitino, is presented. Data collected during 2000 with the DELPHI detector at centre-of-mass energies from 204 to 208 GeV were analysed and combined with all the data collected from 1995 to 1999 at lower energies. [...]

Search for charginos nearly mass-degenerate with the lightest neutralino / DELPHI Collaboration
A search for charginos with masses close to the mass of the lightest neutralino is reported, based on the data collected with the DELPHI detector at LEP from 1995 to 1997 at centre-of-mass energies between 130 and 183 GeV. The signature of a photon at high transverse momentum radiated from the initial state reduces the two-photon background to acceptable rates, thus making the mass differences between a few hundred MeV/c^2 and 3 GeV/c^2 detectable.
