    Description: ALICE measured the nuclear modification factor ($R_{AA}$) and elliptic flow ($\nu_{2}$) of D mesons ($D^{0}$, $D^{+}$, $D^{⁎+}$ and $D^{s+}$) in semi-central Pb–Pb collisions at $\sqrt{s_{NN}} =5.02$ TeV. The increased amount of data in semi-central Pb–Pb events obtained with the LHC Run 2 provides access to more precise measurements for the $R_{AA}$ and the non-strange D-meson $\nu_{2}$ with respect to Run 1 results, as well as to the first measurement of the $D_{s}$ -meson $\nu_{2}$ at LHC energies. The first application of the Event Shape Engineering technique in the analysis of the $\nu_{2}$ coefficient of $D^{0}$ and $D^{+}$ mesons is also illustrated.

    Description: The ALICE collaboration has measured the inclusive charmonium production at forward rapidity in Pb–Pb and p–Pb collisions at sNN=5.02TeV and sNN=8.16TeV , respectively. In Pb–Pb collisions, the J/ ψ and ψ (2S) nuclear modification factors ( R AA ), as well as the J/ ψ elliptic flow ( v2 ) and averaged squared transverse momentum ( 〈pT2〉 ), are presented. In p–Pb collisions, the J/ ψ nuclear modification factor ( R pPb ) as a function of p t and rapidity is presented. In both systems, our measurements are compared to theoretical calculations and to the results at lower energies.

    Description: We report measurements of two jet shapes, the ratio of 2-Subjettiness to 1-Subjettiness ($\it{\tau_{2}}/\it{\tau_{1}}$) and the opening angle between the two axes of the 2-Subjettiness jet shape, which is obtained by reclustering the jet with the exclusive-$\it{k}_{T}$ algorithm \cite{kT} and undoing the final clustering step. The aim of this measurement is to explore a possible change in the rate of 2-pronged objects in Pb-Pb compared to pp due to colour coherence. Coherence effects \cite{ColourCoherence} relate to the ability of the medium to resolve a jet's substructure, which has an impact on the energy loss magnitude and mechanism of the traversing jet. In both collision systems charged jets are found with the anti-$\it{k}_{T}$ algorithm \cite{Anti-kT}, a resolution parameter of $\it{R}=$0.4\ and a constituent cut off of $0.15$ GeV. This analysis uses hadron-jet coincidence techniques in Pb-Pb collisions to reject the combinatorial background and corrects further for background effects...

    Description: We report measurements of two jet shapes, the ratio of 2-Subjettiness to 1-Subjettiness (τ2/τ1) and the opening angle between the two axes of the 2-Subjettiness jet shape, which is obtained by reclustering the jet with the exclusive-kT algorithm [1] and undoing the final clustering step. The aim of this measurement is to explore a possible change in the rate of 2-pronged objects in Pb-Pb compared to pp due to colour coherence. Coherence effects [2] relate to the ability of the medium to resolve a jet’s substructure, which has an impact on the energy loss magnitude and mechanism of the traversing jet. In both collision systems charged jets are found with the anti-kT algorithm [3], a resolution parameter of R =0.4 and a constituent cut off of 0.15 GeV. This analysis uses hadron-jet coincidence techniques in Pb-Pb collisions to reject the combinatorial background and corrects further for background effects by employing various jet shape subtraction techniques and two dimensional unfolding. Measurements of the Nsubjettiness for jet momenta of 40 – 60 GeV/c in Pb-Pb collisions at √sNN = 2.76 TeV and pp collisions at √s = 7 TeV will be presented and compared to PYTHIA simulations.
