$\phi$-meson production at forward rapidity in p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV and in pp collisions at $\sqrt{s}$ = 2.76 TeV / ALICE Collaboration, CERN /ALICE
The first measurement of $\phi$-meson production in p-Pb collisions at a nucleon-nucleon centre-of-mass energy $\sqrt{s_{\rm NN}}$ = 5.02 TeV has been performed with the ALICE apparatus at the LHC. $\phi$ mesons have been identified in the dimuon decay channel in the transverse momentum ($p_{\rm T}$) range $1 < p_{\rm T} < 7$ GeV/c, both in the p-going ($2.03 < y < 3.53$) and the Pb-going ($-4.46 < y < -2.96$) directions, where $y$ stands for the rapidity in the nucleon-nucleon centre-of-mass.

Differential studies of inclusive J/$\psi$ and $\psi(2S)$ production at forward rapidity in Pb–Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV / ALICE Collaboration, CERN /ALICE
The production of J/$\psi$ and $\psi(2S)$ was measured with the ALICE detector in Pb–Pb collisions at the LHC. The measurement was performed at forward rapidity ($2.5 < y < 4$) down to zero transverse momentum ($p_{\rm T}$) in the dimuon decay channel. [...]

Forward-central two-particle correlations\\in p--Pb collisions at sqrt(sNN)= 5.02 TeV / ALICE, CERN /ALICE
Two-particle angular correlations between trigger particles in the forward pseudorapidity range ($2.5 < |\eta| < 4.0$) and associated particles in the central range~($|\eta| < 1.0$) are measured with the ALICE detector in \pPb\ collisions at a nucleon--nucleon centre-of-mass energy of \unit[5.02]{TeV}. The trigger particles are reconstructed using the muon spectrometer, and the associated particles by the central barrel tracking detectors. [...]

Centrality dependence of the nuclear modification factor of charged pions, kaons, and protons in Pb-Pb collisions at 2.76 TeV / Adam, Jaroslav (Prague, Tech. U.) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Aggarwal, Madan Mohan (Panjab U.) ; Aglieri Rinella, Gianluca (CERN) ; Agnello, Michelangelo (INFN, Turin) ; Agrawal, Neelima (Indian Inst.

Transverse momentum (\pt) spectra of pions, kaons, and protons up to $\pt = \gevc{20}$ have been measured in \pbpb collisions at $\snnt{2.76}$ using the ALICE detector for six different centrality classes covering 0-80\%. The proton-to-pion and the kaon-to-pion ratios both show a distinct peak at $\pt \approx \gevc{3}$ in central \pbpb collisions that decreases towards more peripheral collisions. [...]

Centrality dependence of high-pT D meson suppression in Pb-Pb collisions at sqrt(sNN) = 2.76 TeV / Adam, Jaroslav (Prague, Tech. U.) ; Adamova, Dagmar (Rez, Nucl. Phys.

The nuclear modification factor, $\RAA$, of the prompt charmed mesons $\Dzero$, $\Dplus$ and $\Dstar$, and their antiparticles, was measured with the ALICE detector in $\PbPb$ collisions at a centre-of-mass energy $\sqrts = 2.76~\tev$ in two transverse momentum intervals, $5<\pt<8~\gev/c$ and $8<\pt<16~\gev/c$, and in six collision centrality classes. The $\RAA$ shows a maximum suppression of a factor of 5--6 in the 10$\%$ most central collisions. [...]

Measurement of jet quenching with semi-inclusive hadron-jet distributions in central Pb-Pb collisions at ${\sqrt{\bf{s}_{\mathrm {\bf{NN}}}}}$ = 2.76 TeV / ALICE Collaboration
We report the measurement of a new observable of jet quenching in central Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV, based on the semi-inclusive rate of charged jets recoiling from a high transverse momentum (high-$p_{\rm T}$) charged hadron trigger. [...]

Measurement of jet quenching with semi-inclusive hadron-jet distributions in central Pb–Pb collisions at sqrt(sNN) = 2.76 TeV / ALICE, CERN /ALICE
The ALICE Collaboration reports the measurement of a new observable of jet quenching in central Pb–Pb collisions at sqrt(sNN) = 2.76 TeV, based on the semi-inclusive rate of charged jets recoiling from a high transverse momentum (high-pT ) charged hadron trigger. Jets are measured using collinear-safejet reconstruction with infrared cutoff for jet constituents of 0.15 GeV/c, for jet resolution parameters R = 0.2, 0.4 and 0.5. [...]
