- Abstract
- A determination of the hadronic fragmentation functions of the Z0 boson is presented from a study of the inclusive hadron production with the DELPHI detector at LEP. These fragmentation functions were compared with the ones at lower energies, thus covering data in a large kinematic range: 196 ⩽ Q2 ⩽ 8312 GeV2 and View the MathML source. A large scaling violation was observed, which was used to extract the strong coupling constant in second order QCD: αs(MZ) = 0.118 ± 0.005. The corresponding QCD scale for five quark flavours is: View the MathML source.
