We report on charmonium measurements [J/psi(1S), psi’(2S), and chi_c(1P)] in
p+p collisions at sqrt(s)=200 GeV. We find that the fraction of J/psi coming
from the feed-down decay of psi’ and chi_c in the midrapidity region
($|eta|<0.35$) is 9.6+/-2.4% and 32+/-9%, respectively. We also report new,
higher statistics p_T and rapidity dependencies of the J/psi yield via
dielectron decay in the same midrapidity range and at forward rapidity
(1.2<|eta|<2.4) via dimuon decay. These results are compared with measurements
from other experiments and discussed in the context of current charmonium
production models.
