The number of quark ($n_q$) scaling, which is manifested
as $v^{hadron}_{2}(p_T) \approx n_q*v_2(p_T/n_q)$, is an
approximate scaling that comes from the addition of the valence
quark momenta at hadronization. The observation of $n_q$ scaling
has been claimed that a partonic matter with quark-like degrees
of freedom and significant collectivity has been generated in
heavy ion...

A study of the dipole flow (v_1) associated with initial geometry fluctuations is presented using the 2010 Pb-Pb data. This analysis involves a systematic decomposition of the first order Fourier coefficient of the two-particle correlation into a dipole flow component and a global momentum conservation component. The dipolar flow is extracted as function of pT (0.5-10 GeV), centrality (0-50%)...

A baryon anomaly – an increase baryon-to-meson production ratio at intermediate transverse momenta in heavy-ion collisions when compared to proton–proton collisions – is observed at RHIC and the LHC. This effect is usually explained by recombination of constituent quarks during QGP hadronisation, or as a consequence of a strong radial flow developed during the heavy-ion collision. In this...

The ALICE Experiment features low material budget and high resolution tracking, which allow for precise measurements of charged particle production.
The measurement of the antibaryon to baryon ratios ($\bar{B}$/B), in particular, probes the baryon transport and the degree of baryon stopping in high energy collisions, providing insight into the collision dynamics and the structure of baryons....

The measurement of heavy-flavour production provides insights on the properties of the high-density QCD medium created in heavy-ion collisions.
In particular, the comparison of charm production in pp and in Pb-Pb collisions allows to study the mechanism of in-medium energy loss of heavy quarks. Furthermore, since strange quarks are abundant in the medium, the relative yield of D+s mesons with...
