Two-kaon correlations in central Pb + Pb collisions at 158 A GeV/c / NA44 Collaboration
Two-particle interferometry of positive kaons is studied in Pb + Pb collisions at mean transverse momenta $<p_{T}>\approx 0.25$ and 0.91 GeV/c. A three-dimensional analysis was applied to the lower $p_T$ data, while a two-dimensional analysis was used for the higher $p_T$ data. [...]

Strange meson enhancement in Pb - Pb collisions / NA44 Collaboration
The NA44 Collaboration has measured yields and differential distributions of $K^{+}, K^{-}, \pi^{+}, \pi^{-}$ in transverse kinetic energy and rapidity, around the center-of-mass rapidity in 158 AGeV/c Pb + Pb collisions at the CERN SPS. A considerable enhancement of $K^{+}$ production per $\pi$ is observed, as compared to $p + p$ collisions at this energy. [...]

One and two dimensional analysis of 3$\pi$ correlations measured in Pb + Pb interactions / NA44 Collaboration
$\pi^{-}\pi^{-}\pi^{-}$ correlations from Pb+Pb collisions at 158 GeV/c per nucleon are presented as measured by the focusing spectrometer of the NA44 experiment at CERN. The three-body effect is found to be stronger for PbPb than for SPb. [...]

Proton and antiproton distributions at mid-rapidity in proton-nucleus and sulphur-nucleus collisions / NA44 Collaboration
Experiment NA44 has measured proton and antiproton distributions at mid-rapidity in sulphur and proton collisions with nuclear targets at 200 and 450 GeV/c per nucleon respectively. The inverse slopes of transverse mass distributions increase with system size for both protons and antiprotons but are slightly lower for antiprotons [...]

Two-proton correlations near midrapidity in $p$ + Pb and S + Pb collisions at the CERN SPS / NA44 Collaboration
Correlations of two protons emitted near midrapidity in $p$ + Pb collisions at 450 GeV/c and S + Pb collisions at 200 AGeV/c are presented, as measured by the NA44 Experiment. The correlation effect, which arises as a result of final state interactions and Fermi-Dirac statistics, is related to the space-time characteristics of proton emission. [...]

Production of pions, kaons and protons in pp collisions at $\sqrt{s}$ = 900 GeV with ALICE at the LHC / ALICE Collaboration
The production of $\pi^+, pi^-, K^+, K^-$, p, and $\bar{p}$ at mid-rapidity has been measured in proton-proton collisions at $\sqrt{s}$ = 900 GeV with the ALICE detector. Particle identification is performed using the specific energy loss in the inner tracking silicon detector and the time projection chamber. [...]

Harmonic decomposition of two-particle angular correlations in Pb-Pb collisions at $\mathbf{\sqrt{s_{\rm NN}} = 2.76}$ TeV / ALICE Collaboration
Angular correlations between unidentified charged trigger ($t$) and associated ($a$) particles are measured by the ALICE experiment in \PbPb\ collisions at $\sqrt{s_{nn}}$=2.76 TeV for transverse momenta $0.25 < p_{T}^{t,\, a} < 15$ GeV/$c$, where $p_{T}^t > p_{T}^a$. The shapes of the pair correlation distributions are studied in a variety of collision centrality classes between 0 and 50% of the total hadronic cross section for particles in the pseudorapidity interval $|\eta| < 1.0$.

D meson elliptic flow in non-central Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76TeV / ALICE Collaboration
Azimuthally anisotropic distributions of $D^0, D^+$ and $D^{*+}$ mesons were studied in the central rapidity region (|y| < 0.8) in Pb-Pb collisions at a centre-of-mass energy $\sqrt{s_{NN}}$ = 2.76 TeV per nucleon-nucleon collision, with the ALICE detector at the LHC. The second Fourier coefficient $\nu_2$ (commonly denoted elliptic flow) was measured in the centrality class 30-50% as a function of the D meson transverse momentum $p_T$, in the range 2-16 GeV/c.
