Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- An upper limit for BR(Z(0) --> 3g) is obtained from a correlation method, which distinguishes statistically between quark and gluon jets by using the difference in their charged particle multiplicity distributions. From the sample of threefold symmetric t

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The measurement of the correlation between the transverse spin components of tau(+)tau(-) pairs collected during 1992 to 1994 with the DELPHI detector at LEP1 is presented. A value C-TT = 0.87 +/- 0.20 (stat.)(-0.12)(+0.10) (syst.) was obtained for the co

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In an analysis of multihadronic events recorded at LEP by DELPHI in the years 1992 through 1994, rapidity correlations of Lambda-Lambda, proton-proton, and Lambda-proton pairs are compared with each other and with the predictions of the string fragmentati

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Event shape and charged particle inclusive distributions are measured using 750000 decays of the Z to hadrons from the DELPHI detector at LEP, These precise data allow a decisive confrontation with models of the hadronization process, Improved tunings of
