20461por Garcia-Montero, Oscar“…Considering only statistical uncertainties, we find that with the projected $\sim 10^{10}$ heavy ion events a measurement of the HBT correlations for $K_\perp<1\, \text{GeV}$ is statistically significant. References [1] E. …”

20462por Prino, Francesco“…In particular, the main goals of the NA60+ experiment will be focused on precision studies of heavy quark and thermal dimuon production in Pb-Pb collisions via a beam-energy scan in the centre-of-mass energy interval $\sqrt{s_{\rm NN}}=5-17$~GeV. The proposed experimental apparatus consists of a vertex telescope located close to the target, and a muon spectrometer located downstream of a hadron absorber. …”

20464por Weiden, Andreas Robert“…As part of this electroweak program, a measurement of the differential and double-differential inclusive Drell-Yan cross-sections with subsequent decay to muon-pairs \begin{equation*} \frac{\mathrm{d} \sigma(pp \to Z/\gamma* \to \mu^+\mu^-)}{\mathrm{d} M_{\mu\mu}}\quad\text{and}\quad \frac{\mathrm{d}^2 \sigma(pp \to Z/\gamma* \to \mu^+\mu^-)}{\mathrm{d} y\, \mathrm{d} M_{\mu\mu}} \end{equation*} is performed in the range $10.5 < M_{\mu\mu} < 110$ GeV/$c^2$ and $2 < y < 4.5$. The cross-section measurement benefits from the high-precision calibration of the absolute luminosity at LHCb. …”

20466por Lewicki, Maciej Piotr“…Research Objectives The main goal of this work was to identify and obtain spectra of charged hadrons produced in Ar+Sc interactions at six beam momenta in the range of 13A-150A GeV/c. The project is a vital part of the NA61/SHINE programme, which main research goal is to study the collisions of intermediate systems, searching for the signatures of the onset of deconfinement and the critical point. …”

20478por Flor, Fernando Antonio“…In this dissertation, I present evidence supporting a flavor-dependent chemical freeze-out in the crossover region of the QCD phase diagram via SHM calculations of the freeze-out parameters at ALICE and STAR at collision energies ranging from $\sqrt{s_{\rm{NN}}} = $ 11.5 GeV to 5.02 TeV. I also show the system size dependence of $T_\mathrm{ch}$ at vanishing $\mu_\mathrm{B}$ via the same approach in pp, pPb and PbPb collisions at LHC energies – supporting the applicability of the SHM in small collision systems and that flavor-dependent freeze-out parameters lead to a natural explanation of strangeness enhancement from small to large collision systems at ALICE.…”
