 Centrality dependence of the pseudorapidity density distribution for charged particles in Pb--Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV / Adam, Jaroslav (Prague, Tech. U.) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Aggarwal, Madan Mohan (Panjab U.) ; Aglieri Rinella, Gianluca (CERN) ; Agnello, Michelangelo (Turin Polytechnic ; INFN, Turin) ; Agrawal, Neelima (Indian Inst. Tech., Mumbai) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Aiola, Salvatore (Yale U.) et al. /ALICE We present the charged-particle pseudorapidity density in Pb--Pb collisions at $\sqrt{s_{_{\mathrm{NN}}}}=5.02\,\mathrm{Te\kern-.25exV}$ in centrality classes measured by ALICE. The measurement covers a wide pseudorapidity range from $-3.5$ to $5$, which is sufficient for reliable estimates of the total number of charged particles produced in the collisions.

 Insight into particle production mechanisms via angular correlations of identified particles in pp collisions at $\sqrt{s}=7$ TeV / ALICE Collaboration, CERN /ALICE Two-particle angular correlations were measured in pp collisions at $\sqrt{s}=7$ TeV. The analysis was carried out for pions, kaons, protons, and lambdas, for all particle/anti-particle combinations in the pair. [...] CERN-EP-2016-322.- Geneva : CERN, 2016 - 17.

 Measurement of the production of high-$p_{\rm T}$ electrons from heavy-flavour hadron decays in Pb–Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV / ALICE Collaboration Electrons from heavy-flavour hadron decays (charm and beauty) were measured with the ALICE detector in Pb–Pb collisions at a centre-of-mass of energy $\sqrt{s_{\rm NN}}=2.76$ TeV.

 Anomalous evolution of the near-side jet peak shape in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 2.76 TeV / ALICE Collaboration The measurement of two-particle angular correlations is a powerful tool to study jet quenching in a $p_{\mathrm{T}}$ region inaccessible by direct jet identification.

 Evolution of the longitudinal and azimuthal structure of the near-side peak in Pb–Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV / ALICE Collaboration In two-particle angular correlation measurements, jets give rise to a near-side peak, formed by particles associated to a higher $p_{\mathrm{T}}$ trigger particle.

 Measurement of electrons from beauty-hadron decays in p-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV and Pb-Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV / ALICE Collaboration The production of beauty hadrons was measured via semi-leptonic decays at mid-rapidity with the ALICE detector at the LHC in the transverse momentum interval $1 2016-08-27 08:50  Jet-like correlations with neutral pion triggers in pp and central Pb-Pb collisions at 2.76 TeV / ALICE Collaboration We present measurements of two-particle correlations with neutral pion trigger particles of transverse momenta$8 < p_{\mathrm{T}}^{\rm trig} < 16~\mathrm{GeV}/c$and associated charged particles of$0.5 < p_{\mathrm{T}}^{\rm assoc} < 10~\mathrm{GeV}/c$versus the azimuthal angle difference$\Delta\varphi$at midrapidity in pp and central Pb-Pb collisions at$\sqrt{s_{\mathrm{NN}}}=2.76$TeV with ALICE. The new measurements exploit associated charged hadrons down to$0.5~\mathrm{GeV}/c$, which significantly extends our previous measurement that only used charged hadrons above$3~\mathrm{GeV}/c$.
