title: "Table 5" of "$\phi$ meson production at forward rapidity in Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}=2.76$ TeV"

description: $R_{\mathrm{AA}}$ of the $\phi$ meson as a function of $\langle N_{\mathrm{part}} \rangle$ for $2.5
description: phi meson measurements provide insight into strangeness production, which is one of 
the key observables for the hot medium formed in high-energy heavy-ion 
collisions. ALICE measured phi production through its decay 
in muon pairs in Pb-Pb collisions at SQRT(S_NN) = 2.76 TeV 
in the intermediate transverse momentum range 2 &lt; PT &lt; 5 GeV/c 
and in the rapidity interval 2.5 &lt; y &lt;4. 
The phi yield was measured as a function of the transverse momentum and collision centrality. 
The nuclear modification factor was obtained as a
function of the average number of participating nucleons. 
Results were compared with the ones obtained via the kaon decay channel in the same 
PT range at midrapidity. The values of the nuclear modification factor in the two rapidity 
regions are in agreement within uncertainties.

description: CERN-LHC. Measurement of the inclusive J/psi polarization at forward rapidity in pp collisions at sqrt{s} = 8 TeV.
Inclusive J/psi polarization parameters is studied in proton-proton collisions at a centre-of-mass energy sqrt{s} = 8 TeV, using the ALICE detector at the CERN LHC. 
The J/psi mesons are reconstructed, via their decay to a muon pair, in the rapidity interval 2.5 &lt; y &lt; 4.0. 
The polarization parameters (lambda_theta, lambda_phi and lambda_thetaphi) of inclusive J/psi, as well as an invariant frame quantity, are studied in both helicity and Collins-Soper frames as a function of transverse momentum (p_T) in the interval 2 &lt; p_T &lt; 15 GeV/c. 
The p_T integrated results are projected in 2-D parameter-space.
The measurements exhibit no polarization of inclusive J/psi within experimental uncertainties. 
In the paper, results are compared to previous measurements at sqrt{s} = 7 TeV from ALICE and LHCb, and also to up-to-date NLO predictions of the Color-Singlet-Model and the NRQCD calculation at sqrt{s} = 8 TeV.
