Abstract
An analysis of inclusive production of KO and the meson resonances K( +/-)(892), rho(0)(770), f(0)(975) and f(2)(1270) in hadronic decays of the Z(0) is presented, based on about 973,000 multihadronic events co llected by the DELPHI detector at LEP during 1991 and 1992. Overall mu ltiplicities have been determined as 1.962 +/- 0.060 K-0 mesons, 0.712 +/- 0.067 K(+/-)(892) and 1.21 +/- 0.15 rho(0)(770) per hadronic Z(0 ) decay. The average multiplicities of f(0)(975) for scaled momentum, x(p) = p/p(beam), in the range 0.05 less than or equal to x(p) less th an or equal to 0.6 and of f(2)(1270) for 0.05 less than or equal to x( p) less than or equal to 1.0 are 0.098 +/- 0.016 and 0.170 +/- 0.043 r espectively. The f(0)(975) and rho(0)(770) x(p)-spectra have p similar shapes. The f(2)(1270)/rho(0)(770) ratio increases with x(p). The ave rage multiplicities and the differential cross sections are compared w ith the JETSET Parton Shower model. The model with default parameters fails to reproduce the experimental K-0 momentum spectrum at low momen tum, describes the K(+/-)(892) and rho(0)(770) x(p)-spectrum shapes, but significantly overestimates their production rates.
