Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The hadronic fragmentation functions of the various quark flavours and of gluons are measured in a study of the inclusive hadron production from Z(0) decays with the DELPHI detector and are compared with the fragmentation functions measured elsewhere at e

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The hadronic structure of the decay of the tau lepton to three charged particles, tau --> 3 pi nu(tau), is studied using data collected by the DELPHI detector at LEP between 1992 and 1995. The invariant mass of the 3 pi system, m(3 pi), is fitted using th

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Using D*+ mesons exclusively reconstructed in the DELPHI detector at LEP, an excess of 66 +/- 14(stat.) events is observed in the D(*+)pi(+)pi(-) final state with a mass of 2637 +/- 2(stat.) +/- 6(syst.) MeV/c(2) and a full width smaller than 15 MeV/c(2)

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- A sample of about 1.4 million hadronic Z decays, selected among the data recorded by the DELPHI detector at LEP during 1994, was used to measure for the first time the momentum spectra of K+, K-0, p, Lambda and their antiparticles in gluon and quark jets.

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
