Sci.) ; Akindinov, Alexander (Unlisted) et al.
A central question in strong-interaction physics, governed by quantum chromodynamics (QCD), is whether femto-scale droplets of quark--gluon plasma (QGP) form in small collision systems involving projectiles significantly smaller than heavy ions. Collisions of light ions such as $^{16}$O and $^{20}$Ne offer a unique opportunity to probe the emergence of collective behavior in QCD matter. [...]

The University of Bergen is involved in developing two calorimeters: the pixel section ofthe Electromagnetic Forward Calorimeter for the ALICE Upgrade to be installed during LS3 fordata-taking in the period 2029–2032 and the Digital Tracking Calorimeter for the proton ComputedTomography prototype. Both designs utilize pixel sensors and require a reliable connection to thereadout which is positioned approximately 5 meters away. [...]

Direct measurements of the $\rho^0$p interaction have remained so far elusive, with most insights derived indirectly from photoproduction or low-energy partial wave analyses. This letter presents the first direct observation of the $\rho^0$p interaction, obtained through two-particle correlations measured in high-multiplicity, ultrarelativistic proton-proton collisions at $\sqrt{s} = 13$ TeV by the ALICE Collaboration at the LHC.

The first measurement at midrapidity ($|y|< 0.5$) of the production yield of the strange-charm baryons $\Xi_{\rm c}^+$ and $\Xi_{\rm c}^0$ as a function of charged-particle multiplicity in proton$-$proton collisions at $\sqrt{s}=13$ TeV with the ALICE experiment at the LHC is reported. The $\Xi_{\rm c}^+$ baryon is reconstructed via the $\Xi_{\rm c}^+ \rightarrow \Xi^- \pi^+ \pi^+$ decay channel in the range $ 4 < p_{\rm T} <12$ GeV/$c$, while the $\Xi_{\rm c}^0$ baryon is reconstructed via both the $\Xi_{\rm c}^0 \longrightarrow \Xi^- \pi^+$ and $\Xi_{\rm c}^0 \rightarrow {\rm e}^+ \nu_{\rm e}$ decay channels in the range $2 < p_{\rm T} <12$ GeV/$c$.

/ALICE
Ultrarelativistic heavy-ion collisions produce a state of hot and dense strongly interacting QCD matter called quark-gluon plasma (QGP). On an event-by-event basis, the volume of the QGP in ultracentral collisions is mostly constant, while its total entropy can vary significantly due to quantum fluctuations, leading to variations in the temperature of the system.
