  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • Infrared and collinear safe event shape distributions and their mean values are determined using the data taken at five different centre of mass energies above M-Z with the DELPHI detector at LEP. From the event shapes, the strong coupling alpha(s) is ext

  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • Inclusive charged hadron distributions as obtained from the DELPHI measurements at 130, 136, 161, 172 and 183 GeV are presented as a function of the variables rapidity, xi(p), p and transversal momenta. Data are compared with event generators and with MLL

  • Tidskriftsartikel (refereegranskat)abstract
    • A sample of 2.2 million hadronic Z decays, selected from the data recorded by the DELPHI detector at LEP during 1994-1995 was used for an improved measurement of inclusive distributions of pi (+), K+ and p and their antiparticles in gluon and quark jets.

  • Tidskriftsartikel (refereegranskat)abstract
    • Production of Sigma(-) and Lambda(1520) in hadronic Z decays has been measured using the DELPHI detector at LEP. The Sigma(-) is directly reconstructed as a charged track in the DELPHI microvertex detector and is identified by its Sigma --> n pi decay lea

  • Tidskriftsartikel (refereegranskat)abstract
    • The longitudinal polarization of the Lambda(b) baryon is measured at the LEP e(+)e(-) collider by DELPHI. It is determined from the charged lepton and neutrino energy spectra in 249 +/- 19 Lambda(b) semileptonic decays reconstructed in approximate to 3.5
