Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- From a data sample of 9.98 pb(-1) integrated luminosity, collected by DELPHI at a centre-of-mass energy of 172 GeV, 118 events were selected as W-pair candidates. From these, the branching fraction Br(W --> q (q) over bar) was measured to be 0.660(-0.037)

Measurement of trilinear gauge couplings in e(+)e(-) collisions at 161 GeV and 172 GeV

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Trilinear gauge boson couplings are measured using data taken by DELPHI at 161 GeV and 172 GeV, Values for WWV couplings (V = Z,gamma) are determined from a study of the reactions e(+)e(-) --> W+W- and e(+)e(-) --> We nu, using differential distributions

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Decays of W+/- bosons, produced at LEP2, have been used to measure the \V-cs\ element of the Cabibbo-Kobayashi-Maskawa matrix. Values for \V-cs\ were extracted both from the measured hadronic branching ratio of W+/- decays and by tagging the flavour of ha

Observation of charge-ordering in particle production in hadronic Z(0) decay

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Analysis of the rapidity structure of charge correlations in hadronic events from Z(0) decays gives evidence for chain-like charge-ordering of particle production along the thrust axis, as predicted by 'QCD-motivated' string-like fragmentation models. (C)

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The DELPHI experiment at LEP uses Ring Imaging Cherenkov detectors for particle identification. The good understanding of the RICH detectors allows the identification of charged pions, kaons and protons, covering the full momentum range from 0.7 < p < 45.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents results on charged Higgs boson production, based on LEP data collected at root s = 172 GeV, that complement the previous DELPHI results obtained at centre of mass energies up to 161 GeV. The charged Higgs bosons are assumed to be pair

- A search for neutral and charged Higgs bosons has been performed in the data collected by the DELPHI detector at centre-of-mass energies of 161 GeV and 172 GeV. The analysis assumes either the pair-production of charged Higgs bosons, H+/-, or the producti

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Two-particle angular correlations in jet cones have been measured in e(+)e(-) annihilation into hadrons at LEP energies (root s = 91 and 183 GeV) and are compared with QCD predictions using the LPHD hypothesis. Two different functions have been tested. Wh
