Quarkonium measurements at forward rapidity with ALICE at the LHC / Shaikh, Wadut
Heavy quarks are produced at the first instant of a nucleus--nucleus collision and therefore are an important tool to study the subsequent high energy-density medium formed in ultra-relativistic heavy-ion collisions. [...]

Production of charged pions, kaons and (anti-)protons in Pb-Pb and inelastic pp collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adhya, Souvik Priyam (Calcutta, VECC) ; Adler, Alexander (Goethe U., Frankfurt, Inst.

Tech., Mumbai ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) et al.
Mid-rapidity production of $\pi^{\pm}$, $\rm{K}^{\pm}$ and ($\overline{\rm{p}}$)p measured by the ALICE experiment at the LHC, in Pb-Pb and inelastic pp collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV, is presented. The invariant yields are measured over a wide transverse momentum ($p_{\rm{T}}$) range from hundreds of MeV/$c$ up to 20 GeV/$c$. [...]

Measurement of electrons from semileptonic heavy-flavour hadron decays at mid-rapidity in pp and Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adhya, Souvik Priyam (Calcutta, VECC) ; 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 ; Indian Inst. Tech., Mumbai ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) et al.
The differential invariant cross section as a function of transverse momentum ($p_\rm{T}$) of electrons from semileptonic heavy-flavour hadron decays was measured at mid-rapidity in proton-proton (pp) collisions at $\sqrt{s}=5.02$ TeV in the $p_\rm{T}$ interval 0.5-10 GeV/$c$, as well as the invariant yield in central (0-10%), semi-central (30-50%) and peripheral (60-80%) lead-lead (Pb-Pb) collisions at $\sqrt{s_{\rm{NN}}}=5.02\text{ TeV}$ in the $p_\rm{T}$ intervals 0.5-26 GeV/$c$ (0-10% and 30-50%) and 0.5-10 GeV/$c$ (60-80%). The modification of the electron yield with respect to what is expected for an incoherent superposition of nucleon--nucleon collisions is evaluated by measuring the nuclear modification factor $R_{\mathrm{AA}}$.

Measurement of the (anti-)$^{3}$He elliptic flow in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV / ALICE Collaboration, CERN /ALICE
The elliptic flow ($v_{2}$) of (anti-)$^{3}$He is measured in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV in the transverse-momentum ($p_{\rm T}$) range of 2-6 GeV/$c$ for the centrality classes 0-20%, 20-40%, and 40-60% using the event-plane method. This measurement is compared to that of pions, kaons, and protons at the same center-of-mass energy [...]

Measurements of inclusive jet spectra in pp and central Pb–Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys.

This article reports measurements of the $p_{\rm{T}}$-differential inclusive jet cross-section in pp collisions at $\sqrt{s}$ = 5.02 TeV and the $p_{\rm{T}}$-differential inclusive jet yield in Pb-Pb 0-10% central collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV. Jets were reconstructed at mid-rapidity with the ALICE tracking detectors and electromagnetic calorimeter using the anti-$k_{\rm{T}}$ algorithm. [...]
