abstract
We present the charged-particle pseudorapidity density in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02\,\mathrm{Te\kern-.25exV}$ in centrality classes measured by ALICE. The measurement covers a wide pseudorapidity range from $-3.5$ to $5$, which is sufficient for reliable estimates of the total number of charged particles produced in the collisions. For the most central (0-5%) collisions we find $21\,400\pm 1\,300$ while for the most peripheral (80-90%) we find $230\pm 38$. This corresponds to an increase of $(27\pm4)\%$ over the results at $\sqrt{s_{\mathrm{NN}}}=2.76\,\mathrm{Te\kern-.25exV}$ previously reported by ALICE. The energy dependence of the total number of charged particles produced in heavy-ion collisions is found to obey a modified power-law like behaviour. The charged-particle pseudorapidity density of the most central collisions is compared to model calculations --- none of which fully describes the measured distribution. We also present an estimate of the rapidity density of charged particles. The width of that distribution is found to exhibit a remarkable proportionality to the beam rapidity, independent of the collision energy from the top SPS to LHC energies.

Relative transverse activity as a probe of collectivity-like long-range correlations in pp collisions at $\sqrt{s}=13$ TeV
In PYTHIA 8 pp collisions at 13 TeV, the highest-RT events develop a long-range near-side ridge in R2^CI, while P2^CI and charge-dependent correlators do not.

Isentropic thermodynamics across the hadron-quark mixed phase in a two-phase model with a PNJL quark description
In a two-phase RMF+PNJL model, isentropic trajectories through the hadron-quark mixed phase heat at low entropy per baryon and cool near the critical end point, with entropy-dependent speed-of-sound structures.

Scaling of soft QGP signatures in relativistic lead, xenon and oxygen collisions in EPOS4
EPOS4 with UrQMD reproduces bulk yields, spectra, pT fluctuations and flow in Pb-Pb and Xe-Xe collisions, and predicts sizable elliptic flow in O-O collisions.

Charm quark production in heavy-ion collisions as a signature of pre-equilibrium
Charm quark production from the pre-equilibrium phase contributes non-negligibly to the total yield in heavy-ion collisions and may allow inference of pre-equilibrium properties when combined with better initial-state...

Study of the hottest droplet of fluid through correlations and fluctuations of collective variables
The thesis uses event-by-event fluctuations and correlations of collective flow and mean transverse momentum to propose new probes of the initial state, explain the ATLAS [pT]-variance fall, and constrain nuclear deformation.
