 D meson elliptic flow in non-central PbPb collisions at sqrt(s_NN)=2.76 TeV /ALICE Anisotropic patterns in the azimuthal distribution of D0, D+ and D* mesons were studied with the ALICE detector in Pb-Pb collisions at the LHC, at a centre-of-mass energy sqrt(s_NN)=2.76 TeV per nucleon--nucleon collision. In particular, in the centrality class 30-50 %, the second harmonic Fourier coefficient v2 (indicated as elliptic flow) was measured as a function of the D meson transverse momentum.

 Performance of the ALICE V0 system /ALICE ALICE is an LHC experiment devoted to the study of strongly interacting matter in proton--proton, proton--nucleus and nucleus--nucleus collisions at ultra-relativistic energies. The ALICE VZERO system, made of two scintillator arrays at asymmetric positions, one on each side of the interaction point, plays a central role in ALICE.

 Mid-rapidity anti-baryon to baryon ratios in pp collisions at $\sqrt{s}$ = 0.9, 2.76 and 7 TeV measured by ALICE / ALICE Collaboration The ratios of yields of anti-baryons to baryons probes the mechanisms of baryon-number transport. Results for anti-proton/proton, anti-$\Lambda/\Lambda$, anti-$\Xi^{+}/\Xi^{-}$ and anti-$\Omega^{+}/\Omega^{-}$ in pp collisions at $\sqrt{s}$ = 0.9, 2.76 and 7 TeV, measured with the ALICE detector at the LHC, are reported.

 Centrality dependence of the pseudorapidity density distribution for charged particles in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV / ALICE Collaboration We present the first wide-range measurement of the charged-particle pseudorapidity density distribution, for different centralities (the 0-5%, 5-10%, 10-20%, and 20-30% most central events) in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV at the LHC.

 Centrality dependence of $\pi$, K, p production in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV / ALICE Collaboration In this paper measurements are presented of $\pi^\pm, K^\pm$, p and $\bar p$ production at mid-rapidity (|y| < 0.5), in Pb–Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV as a function of centrality. The measurement covers the transverse momentum ($p_T$) range from 100, 200, 300 MeV/c up to 3, 3, 4.6 GeV/c, for $\pi$, K, and p respectively.

 Long-range angular correlations on the near and away side in p-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV / ALICE Collaboration Angular correlations between charged trigger and associated particles are measured by the ALICE detector in p-Pb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV for transverse momentum ranges within 0.5 < pT,assoc < pT,trig < 4 GeV/c. The correlations are measured over two units of pseudorapidity and full azimuthal angle in different intervals of event multiplicity, and expressed as associated yield per trigger particle.

 Charged kaon femtoscopic correlations in pp collisions at $\sqrt{s}=7$ TeV / ALICE Collaboration Correlations of two charged identical kaons (K$^{ch}$ K$^{ch}$) are measured in pp collisions at $\sqrt{s}$=7 TeV by the ALICE experiment at the Large Hadron Collider (LHC). One-dimensional K$^{ch}$ K$^{ch}$ correlation functions are constructed in three multiplicity and four transverse momentum ranges.
