- 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
- 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.

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
