J/psi production at high transverse momenta in p plus p and Cu plus Cu collisions at [sqrt] s(NN)=200 GeV

The STAR Collaboration at the Relativistic Heavy Ion Collider presents measurements of J/psi-->e+e- at midrapidity and high transverse momentum (pT>5 GeV/c) in p+p and central Cu+Cu collisions at [sqrt]sNN=200 GeV. The inclusive J/psi production cross section for Cu+Cu collisions is found to b...

520 |a The STAR Collaboration at the Relativistic Heavy Ion Collider presents measurements of J/psi-->e+e- at midrapidity and high transverse momentum (pT>5 GeV/c) in p+p and central Cu+Cu collisions at [sqrt]sNN=200 GeV. The inclusive J/psi production cross section for Cu+Cu collisions is found to be consistent at high pT with the binary collision-scaled cross section for p+p collisions. At a confidence level of 97%, this is in contrast to a suppression of J/psi production observed at lower pT. Azimuthal correlations of J/psi with charged hadrons in p+p collisions provide an estimate of the contribution of B-hadron decays to J/psi production of 13%±5%.
