Περίληψη:
DELPHI results are presented on the inclusive production of the neutral
mesons rho(0), f(0)(980), f(2)(1270), K-2(*0)(1430) and f’(2)(1525) in
hadronic Z(0) decays. They are based on about 2 million multihadronic
events collected in 1994 and 1995, using the particle identification
capabilities of the DELPHI Ring Imaging Cherenkov detectors and measured
ionization losses in the Time Projection Chamber. The total production
rates per hadronic Z(0) decay have been determined to be: 1.19 +/- 0.10
for rho(0); 0.164 +/- 0.021 for f(0)(980); 0.214 +/- 0.038 for
f(2)(1270); 0.073 +/- 0.023 for K-2(*0)(1430); and 0.012 +/- 0.006 fur
f’(2)(1525). The total production rates for all mesons and differential
cross-sections for the rho(0), f(0)(980) and f(2)(1270) are compared
with the results of other LEP experiments and with models, (C) 1999
