-
Journal article (peer-reviewed)abstract
- Using data collected in the DELPHI detector at LEP-1, measurements of the inclusive T branching ratios for decay modes containing one, three, or five charged particles have been performed, giving the following results: B-1 equivalent to B T- (particle)(-)

Journal article (other academic/artistic)abstract
- The partial decay width of the Z to b (b) over bar quark pairs has been measured by the DELPHI detector at LEP using data taken in the years 1992 to 1995. Decays of b-hadrons were tagged by several methods using tracks with large impact parameters and/or
