Directed flow of charged particles at mid-rapidity relative to the spectator plane in Pb-Pb collisions at sqrt{s_NN}=2.76 TeV /ALICE
The directed flow of charged particles at midrapidity is measured in Pb-Pb collisions at sqrt{s_NN}=2.76 TeV relative to the collision plane defined by the spectator nucleons. Both, the rapidity odd (v_1^odd) and even (v_1^even) directed flow components are reported. [...]

D meson elliptic flow in non-central Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76TeV / ALICE Collaboration
Azimuthally anisotropic distributions of $D^0, D^+$ and $D^{*+}$ mesons were studied in the central rapidity region (|y| < 0.8) in Pb-Pb collisions at a centre-of-mass energy $\sqrt{s_{NN}}$ = 2.76 TeV per nucleon-nucleon collision, with the ALICE detector at the LHC. [...]

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. [...]

Charge correlations using the balance function in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV / ALICE Collaboration
In high–energy heavy–ion collisions, the correlations between the emitted particles can be used as a probe to gain insight into the charge creation mechanisms. In this article, we report the first results of such studies using the electric charge balance function in the relative pseudorapidity (∆η) and azimuthal angle (∆φ) in Pb–Pb collisions at √sNN = 2.76 TeV with the ALICE detector at the Large Hadron Collider.
