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.

Transverse momentum distributions and nuclear modification factor of integrated charged particles yield produced in p[Formula: see text]+[Formula: see text]Pb collisions at [Formula: see text] = 5.02 TeV are investigated in mid-rapidity regions of [Formula: see text] at one event multiplicity class 0–5% in the transverse momentum range of [Formula: see text]20 GeV/c. Simulations with EPOS-1.99, EPOS-LHC and QGSJETII-04 are compared with the ALICE data. All three models are in good agreement with each other up to [Formula: see text]3 GeV/c for transverse momentum distributions but after that QGSJETII-04 overpredicts the experimental data. EPOS-LHC seems to describe the experimental data quite well as compared to the other two models. The ratios of the kaons to pions and protons to pions are also presented where again EPOS-LHC provides good agreement with the ALICE data. In case of the nuclear modification factor, for (anti) pions and (anti) kaons, the model distribution is around 1, whereas it is greater than 1 in case of (anti) protons which shows Cronin enhancement.

In this work we compare the nuclear modification factors in proton (deuteron) — nucleus collisions at CERN SPS, FNAL and RHIC energies in a wide pT range. In these experiments the nuclear modification factor has shown an enhancement at pT ≈ 4 GeV /c. The height of this “Cronin peak” depends on the c.m. energy of the collision, as it is subject to stronger shadowing at higher energies. One of the aims of this contribution is to analyze the shadowing phenomenon at lower (2 GeV / c ≲ pT ≲ 4 GeV / c ) and intermediate (4 GeV / c ≲ pT ≲ 8 GeV / c ) transverse momentum. Different shadowing parametrizations are considered and the obtained Cronin peaks are investigated at RHIC and LHC energies.
