Abstract
We report on charmonium measurements [J/ψ (1S), ψ′ (2S), and χ c (1P)] in p+p collisions at √s=200GeV. We find that the fraction of J/ψ coming from the feed-down decay of ψ′ and χ c in the midrapidity region (

y

<0.35) is 9.6±2.4% and 32±9%, respectively. We also present the p T and rapidity dependencies of the J/ψ yield measured via dielectron decay at midrapidity (

<0.35) and via dimuon decay at forward rapidity (1.2<

<2.2). The statistical precision greatly exceeds that reported in our previous publication. The new results are compared with other experiments and discussed in the context of current charmonium production models. © 2012 American Physical Society.
