Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The hadronic structure of the decay of the tau lepton to three charged particles, tau --> 3 pi nu(tau), is studied using data collected by the DELPHI detector at LEP between 1992 and 1995. The invariant mass of the 3 pi system, m(3 pi), is fitted using th

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The splitting processes in identified quark and gluon jets are investigated using longitudinal and transverse observables. The jets are selected from symmetric three-jet events measured in Z decays with the DELPHI detector in 1991-1994. Gluon jets are ide

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
