J/$\psi$ polarization in pp collisions at $\sqrt{s}$=7 TeV / ALICE Collaboration
The ALICE Collaboration has studied J/psi production in pp collisions at $\sqrt{s}$=7 TeV at the LHC through its muon pair decay. The polar and azimuthal angle distributions of the decay muons were measured, and results on the J/$\psi$ polarization parameters lambda_theta and lambda_phi were obtained. [...]

Measurement of charm production at central rapidity in proton-proton collisions at $\sqrt{s}$ = 7 TeV / ALICE Collaboration
The pt-differential inclusive production cross sections of the prompt charmed mesons D0, D+, and D*+ in the rapidity range |y|<0.5 were measured in proton-proton collisions at sqrt(s) = 7 TeV at the LHC using the ALICE detector. Reconstructing the decays D0->K-pi+, D+->K-pi+pi+, D*+->D0pi+, and their charge conjugates, about 8,400 D0, 2,900 D+, and 2,600 D*+ mesons with 1<pt<24 GeV/c were counted, after selection cuts, in a data sample of 3.14x10^8 events collected with a minimum-bias trigger (integrated luminosity L_int = 5/nb).

Particle-yield modification in jet-like azimuthal dihadron correlations in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV / ALICE Collaboration
The yield of charged particles associated with high-pT trigger particles (8 < pT < 15 GeV/c) is measured with the ALICE detector in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV relative to proton-proton collisions at the same energy. The conditional per-trigger yields are extracted from the narrow jet-like correlation peaks in azimuthal di-hadron correlations. [...]

Harmonic decomposition of two-particle angular correlations in Pb-Pb collisions at $\mathbf{\sqrt{s_{\rm NN}} = 2.76}$ TeV / ALICE Collaboration
Angular correlations between unidentified charged trigger ($t$) and associated ($a$) particles are measured by the ALICE experiment in \PbPb\ collisions at $\sqrt{s_{nn}}$=2.76 TeV for transverse momenta $0.25 < p_{T}^{t,\, a} < 15$ GeV/$c$, where $p_{T}^t > p_{T}^a$. The shapes of the pair correlation distributions are studied in a variety of collision centrality classes between 0 and 50% of the total hadronic cross section for particles in the pseudorapidity interval $|\eta| < 1.0$.

Higher harmonic anisotropic flow measurements of charged particles in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV / ALICE Collaboration
We report on the first measurement of the triangular v3, quadrangular v4, and pentagonal v5 charged particle flow in Pb-Pb collisions at 2.76 TeV measured with the ALICE detector at the CERN Large Hadron Collider. We show that the triangular flow can be described in terms of the initial spatial anisotropy and its fluctuations, which provides strong constraints on its origin. [...]

Rapidity and transverse momentum dependence of inclusive J/$\psi$ production in pp collisions at $\sqrt{s}$ = 7 TeV / ALICE Collaboration
The ALICE experiment at the LHC has studied inclusive J/psi production at central and forward rapidities in pp collisions at sqrt(s) = 7 TeV. In this Letter, we report on the first results obtained detecting the J/psi through its dilepton decay into e+e- and mu+mu- pairs in the rapidity range |y|<0.9 and 2.5<y<4, respectively, and with acceptance down to zero p_T.

Femtoscopy of $pp$ collisions at $\sqrt{s}$=0.9 and 7 TeV at the LHC with two-pion Bose-Einstein correlations / ALICE Collaboration
We report on the high statistics two-pion correlation functions from pp collisions at $\sqrt{s}$=0.9 TeV and $\sqrt{s}$=7 TeV, measured by the ALICE experiment at the Large Hadron Collider. The correlation functions as well as the extracted source radii scale with event multiplicity and pair momentum. [...]

Two-pion Bose-Einstein correlations in central PbPb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV / ALICE Collaboration
The first measurement of two-pion Bose--Einstein correlations in central PbPb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV at the Large Hadron Collider is presented. We observe a growing trend with energy now not only for the longitudinal and the outward but also for the sideward pion source radius. [...]

Production of pions, kaons and protons in pp collisions at $\sqrt{s}$ = 900 GeV with ALICE at the LHC / ALICE Collaboration
The production of $\pi^+, pi^-, K^+, K^-$, p, and $\bar{p}$ at mid-rapidity has been measured in proton-proton collisions at $\sqrt{s}$ = 900 GeV with the ALICE detector. Particle identification is performed using the specific energy loss in the inner tracking silicon detector and the time projection chamber. [...]
