We present the transverse momentum spectra for charged hadrons as well as for identified particles produced in Au + Au and p + p collisions at [Formula: see text] for different event centralities (minimum bias spectra for p + p) in narrow rapidity ranges (±0.1), for midrapidity and high rapidities (up to 3.8). Nuclear modification factor RAA for identified baryons and mesons, as well as for inclusive charged hadrons, at rapidities from 0 to 3.8 will be shown and discussed.

Abstract In this paper we present a study of in-medium jet modifications performed with JEWEL and PYTHIA 6.4, focusing on the uncertainties related to variations of the perturbative scales and nuclear parton distribution functions (PDFs) and on the impact of the initial and crossover temperature variations of the medium. The simulations are compared to LHC data for the jet spectrum and the nuclear modification factor. We assess the interplay between the choice of nuclear PDFs and different medium parameters and study the impact of nuclear PDFs and the medium on the jet structure via the Lund plane.

Centrality dependence of nuclear modification factor at high pT above 4 GeV /c is studied in nucleus–nucleus collisions at [Formula: see text]. We find that the centrality dependence of the nuclear modification factor can be factorized as a Boltzmann function F(b). Comparing our model calculation with PHENIX data, we further confirm that the high pT spectrum of particles is dominated by surface emission.
