Searches for neutral Higgs bosons in the Standard Model and the MSSM have been performed using data collected by the DELPHI experiment at a centre-of-mass energy of 188.7 GeV, corresponding to an inte...
An analysis of the data collected in 1997 and 1998 with the DELPHI detector at e + e − collision energies close to 183 and 189 GeV was performed in order to extract the hadronic and leptonic fermion-p...
The data collected by DELPHI in 1998 at the centre-of-mass energy of 189 GeV have been used to update the search for charginos nearly mass-degenerate with the lightest supersymmetric particle, which i...
We report on a search for supersymmetry using the DØ detector. The 1994–1996 data sample of s=1.8 TeV pp¯ collisions was analyzed for events containing two leptons (e or μ), two or more jets, and miss...
A search for charginos nearly mass-degenerate with the lightest supersymmetric particle is performed using the 176 pb −1 of data collected at 189 GeV in 1998 with the L3 detector. Mass differences bet...
Sleptons, neutralinos and charginos were searched for in the context of scenarios where the lightest supersymmetric particle is the gravitino. It was assumed that the stau is the next-to-lightest supe...
An update of the searches for charginos and gravitinos is presented, based on a data sample corresponding to the 158 pb −1 recorded by the DELPHI detector in 1998, at a centre-of-mass energy of 189 Ge...
Neutral Higgs bosons of the Standard Model and of the MSSM are searched for in the data collected at a centre-of-mass energy of 188.6 GeV by the ALEPH experiment at LEP, with an integrated luminosity...
The production of single photons has been studied in the reaction e+e- -> gamma + invisible particles at centre-of-mass energies of 183 GeV and 189 GeV. A previously published analysis of events with ...
A search for the decay B ± →K ± K ± π ∓ was performed using data collected by the OPAL detector at LEP. These decays are strongly suppressed in the Standard Model but could occur with a higher branchi...
