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
- From the data collected by DELPHI at LEP in autumn 1995, the multiplicity of charged particles at a hadronic energy of 130 GeV has been measured to be [n(ch)] = 23.84 +/- 0.51(stat) +/- 0.52(syst), When compared to lower energy data, the value measured is

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The average lifetime of b-baryons has been studied using 3 x 10(6) hadronic Z(0) decays collected by the DELPHI detector at LEP. Three methods have been used, based on the measurement of different observables: the proper decay time distribution of 206 ver
