摘要：
Inclusive production of f(0)(980), f(2)(1270) and phi(1020) has been studied is a sample of 4.3 million hadronic Z(0) decays from the OPAL experiment at LEP. Fragmentation functions are reported for the three states. Total inclusive rates are measured to be 0.160 +/- 0.014 f(0), 0.119 +/- 0.016 f(2) and 0.093 +/- 0.004 phi mesons per hadronic Z(0) decay. The production properties of the f(0), including those in three-jet events. are compared with those of the f(2) and phi, and with the Lund string model of hadron production. Ali measured properties are consistent with the hypothesis that the f(0)(980) is a conventional q (q) over bar scalar meson.
