“…The EKS98 valence quark shadowing ratios are used as input since We now turn to the spatial dependence of the shadowing. Since some qualitative spatial dependence has been observed [23] but the exact behavior is unknown, we have tried two different parameterizations for inhomogeneous shadowing in d+Au collisions [11,[24][25][26]. The first, S j P,WS , assumes that shadowing is proportional to the local density, ρ A (r),…”

We explore how nuclear modifications to the nucleon parton distributions affect production of high transverse momentum hadrons in deuteron-nucleus collisions. We calculate the charged hadron spectra to leading order using standard fragmentation functions and shadowing parameterizations. We obtain the d+Au to pp ratio both in minimum bias collisions and as a function of centrality. The minimum bias results agree reasonably well with the BRAHMS data while the calculated centrality dependence underestimates the data and is a stronger function of p T than the data indicate.

Abstract:The measurement of prompt D-meson production as a function of multiplicity in p-Pb collisions at √ s NN = 5.02 TeV with the ALICE detector at the LHC is reported. D 0 , D + and D * + mesons are reconstructed via their hadronic decay channels in the centre-of-mass rapidity range −0.96 < y cms < 0.04 and transverse momentum interval 1 < p T < 24 GeV/c. The multiplicity dependence of D-meson production is examined by either comparing yields in p-Pb collisions in different event classes, selected based on the multiplicity of produced particles or zero-degree energy, with those in pp collisions, scaled by the number of binary nucleon-nucleon collisions (nuclear modification factor); as well as by evaluating the per-event yields in p-Pb collisions in different multiplicity intervals normalised to the multiplicity-integrated ones (relative yields). The nuclear modification factors for D 0 , D + and D * + are consistent with one another. The D-meson nuclear modification factors as a function of the zero-degree energy are consistent with unity within uncertainties in the measured p T regions and event classes. The relative D-meson yields, calculated in various p T intervals, increase as a function of the charged-particle multiplicity. The results are compared with the equivalent pp measurements at √ s = 7 TeV as well as with EPOS 3 calculations.

We explore how nuclear modifications to the nucleon parton distributions affect production of high-p T hadrons in heavy ion collisions. We perform a leading order calculation of the high-p T charged pion, kaon and proton spectra using standard fragmentation functions and shadowing parameterizations.We also consider alternate models of shadowing. Near midrapidity, shadowing is a small effect and cannot explain the large observed suppression of high-p T hadrons. We also consider the isospin difference between protons and nuclei and find that it is also a small effect on high-p T hadron production.
