Measurement of Inclusive $f_1(1285)$ and $f_1(1420)$ Production in $Z$ Decays with the DELPHI Detector
Inclusive production of two $(K\bar K\pi)^0$ 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 $1274\pm4$ and $29\pm12$ MeV for the first peak and $1426\pm4$ and $51\pm14$ MeV for the second. A partial-wav...
