摘要In a Glauber Monte Carlo framework, taking into account the transverse spatial distribution of hard partons in the nucleon, we analyze the nuclear modification factor Rd Au for J/φ in d+Au collisions with EPS09 shadowing parametrization. After the influence of nucleon hard partons distribution is considered, a clearly upward correction is revealed for the dependence of Rd Au on Ncoll in peripheral d+Au collisions, however, an unconspicuous correction is shown for the results versus pT. The theoretical results are in good agreement with the experimental data from PHENIX.
Abstract：In a Glauber Monte Carlo framework, taking into account the transverse spatial distribution of hard partons in the nucleon, we analyze the nuclear modification factor Rd Au for J/φ in d+Au collisions with EPS09 shadowing parametrization. After the influence of nucleon hard partons distribution is considered, a clearly upward correction is revealed for the dependence of Rd Au on Ncoll in peripheral d+Au collisions, however, an unconspicuous correction is shown for the results versus pT. The theoretical results are in good agreement with the experimental data from PHENIX.
(Relativistic heavy-ion collisions (collisions induced by light ions studied to calibrate relativistic heavy-ion collisions should be classified under both 25.75.-q and sections 13 or 25 appropriate to the light ions))
