Charged-particle multiplicity distributions over a wide pseudorapidity range in proton-proton collisions at $\sqrt{s}$ = 0.9, 7 and 8 TeV / ALICE, CERN /ALICE
We present the charged-particle multiplicity distributions over a wide pseudorapidity range (−3.4 < $\eta$ < 5.0) for pp collisions at $\sqrt{s}$ = 0.9, 7, and 8 TeV at the LHC. Results are based on information from the Silicon Pixel Detector and the Forward Multiplicity Detector of ALICE, extending the pseudorapidity coverage of the earlier publications and the high- multiplicity reach.

The transverse momentum (p T ) spectra and elliptic flow coefficient (v 2 ) of deuterons and anti- deuterons at mid-rapidity (|y| < 0.5) are measured with the ALICE detector at the LHC in Pb–Pb √ collisions at s NN = 2.76 TeV. The measurement of the p T spectra of (anti-)deuterons is done up to 8 GeV/c in 0-10% centrality class and up to 6 GeV/c in 10–20% and 20–40% centrality classes. [...]

The azimuthal anisotropy coefficient $v_2$ of prompt D$^0$, D$^+$, D$^{*+}$ and D$_s^+$ mesons was measured in mid-central (30-50% centrality class) Pb-Pb collisions at a centre-of-mass energy per nucleon pair $\sqrt{s_{\rm NN}}=5.02$ TeV, with the ALICE detector at the LHC. The D mesons were reconstructed via their hadronic decays at mid-rapidity, $|y|<0.8$, in the transverse momentum interval $1<p_{\rm T}<24$ GeV/$c$. [...]

Searches for transverse momentum dependent flow vector fluctuations in Pb-Pb and p-Pb collisions at the LHC / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adolfsson, Jonatan (Lund U.) ; Aggarwal, Madan Mohan (Panjab U.) ; Aglieri Rinella, Gianluca (CERN) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Indian Inst. Tech., Mumbai) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Nazeer (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) et al. /ALICE
The measurement of azimuthal correlations of charged particles is presented for Pb--Pb collisions at $\snn=$ 2.76 TeV and p--Pb collisions at $\snn=$ 5.02 TeV with the ALICE detector at the CERN Large Hadron Collider. These correlations are measured for the second, third and fourth order flow vector in the pseudorapidity region $|\eta|<0.8$ as a function of centrality and transverse momentum $\pt$ using two observables, to search for evidence of $p_{\rm T}$-dependent flow vector fluctuations.

Linear and non-linear flow mode in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adolfsson, Jonatan (Lund U.) ; Aggarwal, Madan Mohan (Panjab U.) ; Aglieri Rinella, Gianluca (CERN) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Indian Inst.

The second and the third order anisotropic flow, V 2 and V 3 , are mostly determined by the correspond- ing initial spatial anisotropy coefficients, ε 2 and ε 3 , in the initial density distribution. In addition to their dependence on the same order initial anisotropy coefficient, higher order anisotropic flow, V n (n > 3), can also have a significant contribution from lower order initial anisotropy coefficients, which leads to mode-coupling effects.

We report measurements of the inclusive J/$\psi$ yield and average transverse momentum as a function of charged-particle pseudorapidity density ${\rm d}N_{\rm ch}/{\rm d}\eta$ in p-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV with ALICE at the LHC. The observables are normalised to their corresponding averages in non-single diffractive events. [...]

Flow dominance and factorization of transverse momentum correlations in Pb-Pb collisions at the LHC / ALICE Collaboration
We present the first measurement of the two-particle transverse momentum differential correlation function, P2≡⟨ΔpTΔpT⟩/⟨pT⟩2, in Pb-Pb collisions at sNN=2.76  TeV. Results for P2 are reported as a function of the relative pseudorapidity (Δη) and azimuthal angle (Δφ) between two particles for different collision centralities. [...]

Production of $\pi^0$ and $\eta$ mesons up to high transverse momentum in pp collisions at 2.76 TeV / ALICE Collaboration
The invariant differential cross sections for inclusive $\pi^{0}$ and $\eta$ mesons at midrapidity were measured in pp collisions at $\sqrt{s}=2.76$ TeV for transverse momenta $0.4 < p_{\rm T} < 40$ GeV/$c$ and $0.6 < p_{\rm T} < 20$ GeV/$c$, respectively, using the ALICE detector. This large range in $p_{\rm T}$ was achieved by combining various analysis techniques and different triggers involving the electromagnetic calorimeter (EMCal). [...]
