J/psi production at low transverse momentum in p plus p and d plus Au collisions at root s(NN)=200 GeV uri icon

abstract

  • 2016 American Physical Society. We report on the measurement of J/ production in the dielectron channel at midrapidity (|y|<1) in p+p and d+Au collisions at sNN=200GeV from the STAR experiment at the Relativistic Heavy Ion Collider. The transverse momentum pT spectra in p+p for pT<4GeV/c and d+Au collisions for pT<3GeV/c are presented. These measurements extend the STAR coverage for J/ production in p+p collisions to low pT. The (pT2) from the measured J/ invariant cross section in p+p and d+Au collisions are evaluated and compared to similar measurements at other collision energies. The nuclear modification factor for J/ is extracted as a function of pT and collision centrality in d+Au and compared to model calculations using the modified nuclear parton distribution function and a final-state J/ nuclear absorption cross section.
