Non-linear flow modes of identified particles in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adler, Alexander (Goethe U., Frankfurt, Inst. Inform.) ; Adolfsson, Jonatan (Lund U.) ; Aggarwal, Madan Mohan (Panjab U.) ; Aglieri Rinella, Gianluca (CERN) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Enrico Fermi Ctr., Rome ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) et al.
The $p_{\rm{T}}$-differential non-linear flow modes, $v_{4,22}$, $v_{5,32}$, $v_{6,33}$ and $v_{6,222}$ for $\pi^{\pm}$, $\rm{K}^{\pm}$ , $\rm{K}^{0}_{S}$ , p + $\overline{\rm{p}}$, $\Lambda$ + $\overline{\Lambda}$ and $\phi$-meson have been measured for the first time at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV in Pb-Pb collisions with the ALICE detector at the Large Hadron Collider. The results were obtained with a multi-particle technique, correlating the identified hadrons with reference charged particles from a different pseudorapidity region. [...]

System and event activity dependent inclusive jet production with ALICE / Hou, Yongzhen (Hua-Zhong Normal U., LQLP) /ALICE Collaboration
Jets are produced by processes involving high momentum transfer of initial partons at high energies. Comparing jet production in pp and nucleus-nucleus collisions will allow us to study the jet-quenching effect caused by the hot and dense QCD medium produced in nucleus-nucleus collisions when energetic partons traverse the medium. [...]

Global Track Reconstruction and Data Compression Strategy in ALICE for LHC Run 3 / Rohr, David (CERN ; INFN, Turin)
In LHC Run 3, ALICE will increase the data taking rate significantly, from an approximately 1 kHz trigger readout in minimum-bias Pb--Pb collisions to a 50 kHz continuous readout rate. [...]

Measurement of $\Lambda_{\rm c}^{+}$ baryons and ${\rm D}_{\rm s}^{+}$ mesons in Pb-Pb collisions with ALICE / Vermunt, Luuk (Utrecht U.)
The study of heavy-flavour (charm and beauty) production is important to understand the properties of the Quark-Gluon Plasma (QGP) formed in ultra-relativistic heavy-ion collisions, since heavy quarks are produced in the initial stages of the collisions and subsequently interact with the medium throughout its evolution.

Global baryon number conservation encoded in net-proton fluctuations measured in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adler, Alexander (Goethe U., Frankfurt, Inst. Inform.) ; Adolfsson, Jonatan (Lund U.) ; Aggarwal, Madan Mohan (Panjab U.) ; Aglieri Rinella, Gianluca (CERN) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Enrico Fermi Ctr., Rome ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) et al. /ALICE
Experimental results are presented on event-by-event net-proton fluctuation measurements in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV, recorded by the ALICE detector at the CERN LHC. These measurements have as their ultimate goal an experimental test of Lattice QCD (LQCD) predictions on second and higher order cumulants of net-baryon distributions to search for critical behavior near the QCD phase boundary.

Longitudinal and azimuthal evolution of two-particle transverse momentum correlations in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adler, Alexander (Goethe U., Frankfurt, Inst.

This paper presents the first measurements of the charge independent (CI) and charge dependent (CD) two-particle transverse momentum correlators $G_{2}^{\rm CI}$ and $G_{2}^{\rm CD}$ in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 2.76 TeV by the ALICE collaboration. The correlators are measured as a function of pair separation in pseudorapidity ($\Delta \eta$) and azimuth ($\Delta \varphi$) and as a function of collision centrality. [...]
