Freeze-out radii extracted from three-pion cumulants in pp, p-Pb and Pb-Pb collisions at the LHC /ALICE
In high-energy collisions, the spatio-temporal size of the particle production region can be measured using the Bose-Einstein correlations of identical bosons at low relative momentum. The source radii are typically extracted using two-pion correlations, and characterize the system at the last stage of interaction, called kinetic freeze-out. [...]

K*(892)0 and phi(1020) production in Pb-Pb collisions at sqrt(s_NN) = 2.76 TeV /ALICE
The yields of the K*(892)0 and phi(1020) resonances are measured in Pb-Pb collisions at sqrt(sNN) = 2.76 TeV through their hadronic decays using the ALICE detector. The measurements are performed in multiple centrality intervals at mid-rapidity (|y|<0.5) in the transverse-momentum ranges 0.3<pT<5 GeV/c for the K*(892)0 and 0.5<pT<5 GeV/c for the phi(1020). [...]

The inclusive production cross sections at forward rapidity of J/$\psi$, $\psi$(2S), $\Upsilon$(1S) and $\Upsilon$(2S) are measured in pp collisions at $\sqrt{s}$ = 7 TeV with the ALICE detector at the LHC. The analysis is based on a data sample corresponding to an integrated luminosity of 1.35 pb$^{-1}$. [...]

Performance of the ALICE Experiment at the CERN LHC / ALICE Collaboration
ALICE is the heavy-ion experiment at the CERN Large Hadron Collider. The experiment continuously took data during the first physics campaign of the machine from fall 2009 until early 2013, using proton and lead-ion beams. [...]

Centrality, rapidity and transverse momentum dependence of the J/$\psi$ suppression in Pb-Pb collisions at $\sqrt{s_{NN}}$=2.76 TeV / ALICE Collaboration
The inclusive J/$\psi$ nuclear modification factor ($R_{AA}$) in Pb-Pb collisions at $\sqrt{s_{NN}}$=2.76TeV has been measured by ALICE as a function of centrality in the $e^+e^-$ decay channel at mid-rapidity |y| < 0.8 and as a function of centrality, transverse momentum and rapidity in the $\mu^+\mu^-$ decay channel at forward-rapidity 2.5 < y < 4.The J/$\psi$ yields measured in Pb-Pb are suppressed compared to those in pp collisions scaled by the number of binary collisions.The $R_{AA}$ integrated over a centrality range corresponding to 90% of the inelastic Pb-Pb cross section is 0.72 +- 0.06 (stat.) +- 0.10 (syst.) at mid-rapidity and 0.57 +- 0.01 (stat.) +- 0.09 (syst.) at forward-rapidity.

Two- and three-pion quantum statistics correlations in Pb-Pb collisions at $\sqrt{s_{NN}}$=2.76 TeV at the CERN Large Hadron Collider / ALICE Collaboration
Correlations induced by quantum statistics are sensitive to the spatio-temporal extent as well as dynamics of particle emitting sources in heavy-ion collisions. In addition, such correlations can be used to search for the presence of a coherent component of pion production. [...]
