Abstract

The production of the tensor mesons 𝑓0⁡(1270) and 𝐾*0⁡(1430) and the scalar meson 𝑆⁡(975) has been observed in 𝑒+⁢𝑒− annihilation at 29 GeV center-of-mass energy by use of data obtained with the high-resolution spectrometer at the SLAC 𝑒+⁢𝑒− storage ring PEP. The mean multiplicities for meson momenta greater than 1450 MeV/c are 〈𝑛𝑓0〉=0.11±0.04, 〈𝑛𝐾*0⁡(1430)〉=0.10±0.06, and 〈𝑛𝑆〉=0.05±0.02 per hadronic event. The fragmentation functions of the tensor mesons are in good agreement with the predictions of the Webber cluster model. The data are consistent with a predominant strange-quark content on the 𝑆 meson.
