Περίληψη:
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 less-than-or-equal-to Q2 less-than-or-equal-to 8312 GeV2 and
x (= p(h)/E(beam)) > 0.08. A large scaling violation was observed, which
was used to extract the strong coupling constant in second order QCD:
alpha(s)(M(Z)) = 0.118 +/- 0.005. The corresponding QCD scale for five
quark flavours is: LAMBDA(MS)(5)BAR = 230 +/- 60 MeV.
