The hadronic production cross section and the polarization of psi(2S) meson are measured by using the data from pp collisions at s = 1.96 TeV collected by the Collider Detector at Fermilab. The datasets used correspond to integrated luminosity of 1.1 fb-1 and 800 pb-1, respectively. The decay psi(2S) → mu +mu-- is used to reconstruct psi(2S) mesons in the rapidity range |y(psi(2S))| < 0.6. The coverage of the pT range is 2.0 GeV/c ≤ pT(psi(2S)) < 30 GeV/ c for the cross section analysis and pT ≥ 5 GeV/c for the polarization analysis. For events with pT(psi(2S)) > 2 GeV/c the integrated inclusive cross section multiplied by the branching ratio for dimuon decay is 3.17 +/- 0.04 +/- 0.28 nb. This result agrees with the CDF Run I measurement considering the increased center-of-mass energy from 1.8 TeV to 1.96 TeV. The polarization of the promptly produced psi(2S) mesons is found to be increasingly longitudinal as pT increases from 5 GeV/c to 30 GeV/c. The result is compared to contemporary theory models.
