Strange meson production and an upper limit on the production of a glueball candidate in electron-positron annihilation at 29 GeV
The {eta}(1450) is a glueball candidate. It has been seen in radiative J/{Psi} decays in the channel KK{pi}. A search has been performed for evidence of its production in e{sup +}e{sup {minus}} annihilation at 29 GeV. In order to infer its quark content by comparison with mesons produced in e{sup +}e{sup {minus}} annihilation the cross sections and multiplicities per multihadron event have been measured for the K{sup 0}, K{sup {asterisk}{plus minus}}, K{sup {asterisk}0} and {phi} mesons. These cross sections are new measurements by the TPC. There is no evidence of {eta}(1450) production in three-jet events. It is not possible to distinguish between the contradictory interpretations of the {eta}(1450) as a radial excitation or a glueball with these upper limits. The {eta}(1450) is produced at a level less than the pure ss{phi} meson which may indicate it is mainly ss if it is a qq meson.
