Abstract
We have measured the differential cross section for the inclusive production of ψ(2S) mesons decaying to μ+μ- that were produced in prompt or B-decay processes from pp̄ collisions at 1.96 TeV. These measurements have been made using a data set from an integrated luminosity of 1.1fb-1 collected by the CDF II detector at Fermilab. For events with transverse momentum pT(ψ(2S))>2GeV/c and rapidity | y(ψ(2S))| <0.6 we measure the integrated inclusive cross section σ(pp̄→ψ(2S)X) •Br(ψ(2S)→μ+μ-) to be 3.29±0.04(stat)±0. 32(syst)nb. © 2009 The American Physical Society.
