Charmonium and $e^+e^-$ pair photoproduction at mid-rapidity in ultra-peripheral Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV
The ALICE Collaboration at the LHC has measured the $J/\psi$ and $\psi$' photoproduction at mid-rapidity in ultra-peripheral Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV. [...]

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. [...]

Full Jet Reconstruction in 2.76 TeV pp and Pb-Pb collisions in the ALICE experiment / Reed, Rosi (Yale U. (main))
Measurements of the suppression of high-pT particles and the away-side jets from heavy-ion collisions at RHIC have shown that medium-induced energy loss affects partons produced in the early stage of a heavy-ion collision. [...]

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. [...]
