- Three jet events arising from decays of the Z beson, collected by the DELPHI detector, were used to measure differences in quark and gluon fragmentation. Gluon jets were anti-tagged by identifying b quark jets. Unbiased quark jets came from events with tw

- 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
- The transverse, longitudinal and asymmetric components of the fragmentation function are measured from the inclusive charged particles produced in e(+)e(-) collisions at LEP. As in deep inelastic scattering, these data are important for tests of QCD. The

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In a sample of 3.02 million hadronic Z(0) decays collected by the DELPHI detector, 270 J/psi --> e(+)e(-) candidates have been selected. A search for fully reconstructed B-c(+/-) mesons has yielded one B-c(+/-) --> J/psi pi(+/-) candidate, no B-c(+/-) -->

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Results are presented of a search for pair production of heavy objects decaying into four hadronic jets, as expected for example from associated or pair production of MSSM Higgs bosons, hA or H+H-, using a data sample of 5.9 pb(-1) of e(+)e(-) collisions
