The PHENIX experiment at RHIC measured ω, η and [Formula: see text]-meson production at high pT in p + p, d + Au and Au + Au collisions at [Formula: see text]. Measurements performed in different hadronic decay channels give consistent results. The measured ratios of all three mesons to π0 are found to be flat as a function of pT in p + p collisions and equal to ω/π0 = 0.81 ± 0.02 ± 0.07, η/π0 = 0.48 ± 0.02 ± 0.02 and [Formula: see text]. Nuclear modification factor measured for ω-mesons in central Au + Au collisions is RAA = 0.4 ± 0.15.

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.
