Production Properties of the Orbitally Excited Mesons f0(980), f2(1270), K*02(1430) and f'2(1525) in Z0 Hadronic Decays
Abstract
DELPHI results are presented on the inclusive production of the neutral mesons rho0, f0(980), f2(1270), K*02(1430) and f'2(1525) in hadronic Z0 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 Z0 decay have been determined to be: 1.19 +/- 0.10 for rho0; 0.164 +/- 0.021 for f0(980); 0.214 +/- 0.038 for f2(1270); 0.073 +/- 0.023 for K*02(1430); and 0.012 +/- 0.006 for f'2(1525). The total production rates for all mesons and differential cross-sections for the rho0, f0(980) and f2(1270) are compared with the results of other LEP experiments and with models.
