 $\phi$ meson production at forward rapidity in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV / ALICE Collaboration, CERN $\phi$ 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 $\sqrt{s_{\rm NN}}$ = 2.76 TeV in the intermediate transverse momentum range $2 < p_{\rm T} < 5$ GeV/$c$ and in the rapidity interval 2.5$<$$y$$<4$.

 Measurement of D$^0$, D$^+$, D$^{*+}$ and D$_{\rm s}^+$ production in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV / ALICE Collaboration, CERN We report measurements of the production of prompt D$^0$, D$^+$, D$^{*+}$ and D$_{\rm s}^+$ mesons in Pb-Pb collisions at the centre-of-mass energy per nucleon-nucleon pair $\sqrt{s_{\rm NN}}=5.02$ TeV, in the centrality classes 0-10%, 30-50% and 60-80%. The D-meson production yields are measured at mid-rapidity ($|y|<0.5$) as a function of transverse momentum ($p_{\rm T}$). [...] CERN-EP-2018-066.- Geneva : CERN, 2018 - 23. Draft (restricted): PDF;

 Azimuthally-differential pion femtoscopy relative to the third harmonic event plane in Pb-Pb collisions at $\mathbf{\sqrt{\textit{s}_{_{\rm NN}}}}$ = 2.76 TeV / ALICE Collaboration Azimuthally-differential femtoscopic measurements, being sensitive to spatio-temporal characteristics of the source as well as to the collective velocity fields at freeze out, provide very important information on the nature and dynamics of the system evolution. While the HBT radii oscillations relative to the second harmonic event plane measured recently reflect mostly the spatial geometry of the source, model studies have shown that the HBT radii oscillations relative to the third harmonic event plane are predominantly defined by the velocity fields.
