Flow dominance and factorization of transverse momentum correlations in Pb-Pb collisions at the LHC / ALICE, CERN /ALICE
We present the first measurement of the two-particle transverse momentum differential correlation function, P2 ≡ ∆pT∆pT/pT2 , in Pb–Pb collisions at sqrt(sNN) = 2.76 TeV. Results for P 2 are reported as a function of relative pseudorapidity (∆η) and azimuthal angle (∆φ) between two particles for different collision centralities. [...]

The transverse momentum distributions of the strange and double-strange hyperon resonances ($\Sigma(1385)^{\pm}$, $\Xi(1530)^{0}$) produced in p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV were measured in the rapidity range $-0.5< y_{\rm{CMS}}<0$ for event classes corresponding to different charged-particle multiplicity densities, $\langle{\rm d}N_{\rm{ch}}/{\rm d}\eta_{\rm{lab}}\rangle$.
