$D$-meson and charmed-baryon measurement in $pp$ and $p$-Pb collisions with ALICE at the LHC / Meninno, Elisa (Salerno U. ; INFN, Salerno) /ALICE
$A$ $Large$ $Ion$ $Collider$ $Experiment$ (ALICE) at CERN was designed to study the strongly interacting medium created in heavy-ion collisions at the LHC, the $Quark$-$Gluon$ $Plasma$ (QGP). Heavy quarks (charm and beauty), produced in the early stages of the collision, are among the most powerful probes to investigate QGP properties. [...]

Characterization of ALPIDE Monolithic Active Pixel Sensor for the ALICE Inner Tracking System Upgrade Using the PS Facility at CERN / Kushpil, S (Rez, Nucl. Phys. Inst.) /ALICE
The upgrade of the Inner Tracking System (ITS), which is currently being developed by the ALICE Collaboration, aims at significantly improving the vertex and tracking resolution as well as the readout rate capabilities of the ALICE experiment at CERN. The new ITS detector will be installed during the second long LHC shutdown (LS2) in 2019-2020. [...]

Nuclear modification factor and elliptic flow of open heavy flavours in Pb--Pb collisions with ALICE at the LHC / Zhang, Xiaoming (Hua-Zhong Normal U.) /ALICE
The latest results on the nuclear modification factor ($R_{\rm AA}$) and the elliptic flow ($v_{2}$) of D mesons and heavy-flavour hadron decay leptons in Pb--Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ and $2.76$ TeV measured with ALICE are presented for different centrality classes. The results, obtained in a wide transverse momentum ($p_{\rm T}$) range and in different rapidity regions, provide further information on the properties of the medium.A suppression of a factor of about $3$--$4$ of production yields relative to pp collisions and a positive $v_{2}$ for open heavy-flavour particles are observed in $p_{\rm T}>5$ GeV/$c$ in most central collisions and in intermediate $p_{\rm T}$ region in semi-central collisions, respectively. [...]

Measurements of jets in ALICE / Nattrass, Christine (Tennessee U.) /ALICE
High energy collisions of heavy nuclei permit the study of nuclear matter at high temperatures and energy densities. Under these conditions the fundamental theory for strong interactions, QCD, predicts a phase transition to a plasma of quarks and gluons. [...]

Recent results on (anti-)(hyper-)nuclei production in pp, p-Pb and Pb-Pb collisions with ALICE / Trogolo, Stefano (INFN, Turin ; Turin U.) /ALICE
The ALICE Collaboration has collected a large data sample of Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV in 2015 at the Large Hadron Collider (LHC), which is complementary to that at $\sqrt{s_{\rm{NN}}}$ = 2.76 TeV from Run 1. In these collisions, a great variety of (anti-)(hyper-)nuclei is produced, namely deuteron, triton, $^3$He, $^4$He, hypertriton ($^3_{\Lambda}$H) and their antiparticles. [...]

Open heavy-flavour production in p-Pb collisions measured with ALICE at the LHC / Terrevoli, Cristina (INFN, Padua ; Padua U.) /ALICE
Heavy flavours are sensitive probes of the hot and dense quark-gluon plasma formed in high-energy nucleus-nucleus collisions. Measurements of their production in p--Pb collisions are crucial for the interpretation of heavy-ion results, because they allow to investigate the cold nuclear matter effects.In addition, the study of heavy-flavour $p_{\rm T}$ modification in high-multiplicity p--Pb collisions could give insight into the possible presence of collective effects.The measurements of open heavy-flavour production performed with ALICE at the LHC in p--Pb collisions at$\sqrt{s_{\rm{NN}}}$= 5.02 TeV are presented [...]

Strangeness production in Pb-Pb collisions with ALICE at the LHC / Kalinak, Peter (Kosice, IEF) /ALICE
We present new ALICE results on the production of strange and multi-strange hadrons in Pb--Pb collisions at the top LHC energy of $\sqrt{s_{\rm NN}}$ = 5.02 TeV.Strangeness production measurements are powerful tools for the study of the thermal properties of the deconfined state of QCD matter, the Quark-Gluon Plasma.Thanks to its unique tracking and PID capabilities, ALICE is able to measure weakly decaying particles through the topological reconstruction of the identified hadron decay products.Transverse momentum spectra of $\mathrm{K}^{0}_{S}$, $\Lambda$, $\Xi$ and $\Omega$ at central rapidity are presented as function of the collision centrality.The so-called baryon anomaly in the ratio $\Lambda$/$\mathrm{K}^{0}_{S}$ is examined to probe particle production mechanisms: the position of the peak is sensitive to recombination proces ses, the high-$p_{\rm T}$ part can provide revealing insights on fragmentation and, finally, the steepness of the rising trend featuring for $p_{\rm T} \lesssim$ 2 GeV/$c$ can be connected to the hydrodynamic expansion of the system.In order to study strangeness enhancement, hyperon yields are normalised to the measurements of pion production in the corresponding centrality classes.Comparisons to lower energy results as well as to different collision systems will be shown. This offers a complete experimental picture that is used as a benchmark for commonly adopted phenomenological models, such as the thermal statistical hadronisation approach..

Low mass dielectron measurements in pp, p-Pb, and Pb-Pb collisions with ALICE at the LHC / Bailhache, Raphaelle (Frankfurt U.) /ALICE
In ultra-relativistic heavy-ion collisions, correlated dielectron pairs are of particular interest since they are produced at all stages of the reaction and leave the dense medium without final state interactions. Therefore, the measurement of low mass dielectrons provides information on the properties of the hot and dense medium created in such collisions. [...]
