We report recent measurements of mesonic resonance production in pp, p–Pb, Pb–Pb and Xe–Xe collision systems with the ALICE detector at LHC energies. Integrated particle yields, mean transverse momenta and particles ratios of mesonic resonances like ρ(770)0, K*(892)0 and Φ(1020) as a function of the charged particle multiplicity are presented. These measurements allow us to have better understanding of properties of the hadronic medium and hadrochemistry of the particle production from large ( Pb–Pb and Xe–Xe) to small systems ( pp, p–Pb). The flavour dependence of parton energy loss is also studied by measuring the nuclear modification factor, RAA in Pb–Pb at √sNN = 2.76 and 5.02 TeV and Xe–Xe at √sNN = 5.44 TeV collisions.

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.
