Abstract
Inclusive production of two (KK-bar{pi}){sup 0} states in the mass region 1.22-1.56 GeV in Z decay at LEP I has been observed by the DELPHI Collaboration. The measured masses and widths are 1274 {+-} 4 and 29 {+-} 12 MeV for the first peak and 1426 {+-} 4 and 51 {+-} 14 MeV for the second. A partial-wave analysis has been performed on the (KK-bar{pi}){sup 0} spectrum in the mass range; the first peak is consistent with the quantum numbers IG(JPC) = 0+(0-+/1++) and the second with IG(JPC) = 0+(1++). These measurements, as well as their total hadronic production rates per hadronic Z decay, are consistent with the mesons of the type nn-bar, where n {l_brace}u,d{r_brace}. They are very likely to be the f1(1285) and the f1(1420), respectively.
