First measurement of f2-prime (1525) production in Z0 hadronic decays

Inclusive production of the f'_{2}(1525) in hadronic Z^{0} decays has been studied in data collected by the DELPHI detector at LEP. The Ring Imaging Cherenkov detectors were important tools in the identification of the decay f'_{2}(1525)\rightarrow K^+K^-. The average number of f'_{2}(1525) produced per hadronic Z decay, N_{f^\prime_2} = 0.020 \pm 0.005\mbox{ (stat)} \pm 0.006\mbox{ (syst)}, and the momentum distribution of the f'_{2}(1525) have both been measured.
