Tidskriftsartikel (refereegranskat)abstract
- 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

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The value of the Lr quark, mass at the M-Z scale defined in the <(MS)over bar> renormalization scheme, m(b)(M-Z), was determined using 2.8 million hadronic Z decays collected during 1992-1994 by the DELPHI detector to be m(b)(M-Z) = 2.67 +/- 0.25 (stat.)

Tidskriftsartikel (refereegranskat)abstract
- The data collected with the DELPHI detector at centre-of-mass energies between 130 and 172 GeV, during LEP operation in 1995 and 1996, have been used to determine the hadronic and leptonic cross-sections and leptonic forward-backward asymmetries. In addit

Tidskriftsartikel (refereegranskat)abstract
- 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-pair cross-sections, as well as the leptonic forward-ba

Measurement and interpretation of the W-pair cross-section in e(+)e(-) interactions at 161 GeV

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In 1996 LEP ran at a centre-of-mass energy of 161 GeV, just above the threshold of W-pair production. DELPHI accumulated data corresponding to an integrated luminosity of 9.93 pb(-1), and observed 29 events that are considered as candidates for W-pair pro

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- B-d(0) meson oscillations are measured in hadronic Z(0) decays using the charge of a lepton or the mean charge of an event hemisphere to sign the presence of a b or a (b) over bar quark when it is produced, and using the charge of a lepton emitted at larg

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Correlations between pions from different W's in e(+)e(-) --> W+W- events are studied using data collected by the DELPHI detector at LEP running at a centre-of-mass energy of 172 GeV in 1996. At the present level of statistics, no enhancement of the corre
