Abstract
We present a study of the production of and in inelastic collisions at and 630 GeV using data collected by the CDF experiment at the Fermilab Tevatron. Analyses of and multiplicity and transverse momentum distributions, as well as of the dependencies of the average number and of and on charged particle multiplicity, are reported. Systematic comparisons are performed for the full sample of inelastic collisions, and for the low and high momentum transfer subsamples, at the two energies. The distributions extend above , showing a higher than previous measurements. The dependence of the mean on the charged particle multiplicity for the three samples shows a behavior analogous to that of charged primary tracks.
