Abstract
We have measured the differential cross section for the inclusive production of ψ(2S) mesons decaying to μ[superscript +]μ[superscript -] that were produced in prompt or B-decay processes from pp̅ collisions at 1.96 TeV. These measurements have been made using a data set from an integrated luminosity of 1.1 fb[superscript -1] collected by the CDF II detector at Fermilab. For events with transverse momentum p[subscript T](ψ(2S))>2 GeV/c and rapidity |y(ψ(2S))|<0.6 we measure the integrated inclusive cross section σ(pp̅ →ψ(2S)X)·Br(ψ(2S)→μ[superscript +]μ[superscript -]) to be 3.29±0.04(stat)±0.32(syst) nb.
