P. Abreu et al., Measurement of inclusive rho(0), f(0)(980), f(2)(1270), K-2(*0)(1430) and f '(2)(1525) production in Z(0) decays, PHYS LETT B, 449(3-4), 1999, pp. 364-382
DELPHI results are presented on the inclusive production of the neutral mes
ons rho(0), f(0)(980), f(2)(1270), K-2(*0)(1430) and f'(2)(1525) in hadroni
c Z(0) decays. They are based on about 2 million multihadronic events colle
cted in 1994 and 1995, using the particle identification capabilities of th
e 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 m
