 Symmetry plane correlations in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$TeV A newly developed observable for correlations between symmetry planes, which characterize the direction of the anisotropic emission of produced particles, is measured in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV with ALICE. [...] CERN-EP-2023-012 ; arXiv:2302.01234. - 21 p. Fulltext

 A multi-differential investigation of strangeness production in pp collisions with ALICE / Schotter, Romain (Strasbourg, IPHC ; Strasbourg Observ.) In these proceedings, two multi-differential analyses performed in pp collisions collected by the ALICE collaboration during the LHC Run 2 are presented. [...] arXiv:2302.00454. - 4 p. Fulltext

 Symmetry plane correlations in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV / ALICE Collaboration, CERN /ALICE A newly developed observable for correlations between symmetry planes, which characterize the direction of the anisotropic emission of produced particles, is measured in Pb--Pb collisions at $\sqrt{s_\text{NN}}$~=~2.76~TeV with ALICE. This so-called Gaussian Estimator allows for the first time the study of these quantities without the influence of correlations between different flow amplitudes.

 Measuring $\mu_{B}$ at the LHC with ALICE / Ciacco, Mario The baryon chemical potential $\mu_B$ is a fundamental parameter for the statistical mechanical description of particle production in heavy-ion collisions: its value encodes the average net baryon content of the fireball at chemical freeze-out.

 Production measurements of heavy quarks in pp collisions at $\sqrt{s}$ = 13 TeV with the ALICE detector / Shaba, Tebogo Joyce (Cape Town U.) Heavy-flavour production measurements in pp collisions are important tools to test theoretical models based on perturbative quantum chromodymanics (pQCD) and to investigate the heavy-quark hadronization mechanisms.

 ALICE upgrades during the LHC Long Shutdown 2 / ALICE Collaboration, CERN /ALICE A Large Ion Collider Experiment (ALICE) has been conceived and constructed as a heavy-ion experiment at the LHC. During LHC Runs 1 and 2, it has produced a wide range of physics results using all collision systems available at the LHC. [...] CERN-EP-2023-009.- Geneva : CERN, 2023 Draft (restricted): PDF;
