 Measurement of the lifetime and $\Lambda$ separation energy of $^{3}_{\Lambda}\mathrm H$ / ALICE Collaboration, CERN The most precise measurements to date of the $^{3}_{\Lambda}\mathrm H$ lifetime $\tau$ and $\Lambda$ separation energy ${\rm B}_{\Lambda}$ are obtained using the data sample of Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=$ 5.02 TeV collected by ALICE at the LHC. The $^{3}_{\Lambda}\mathrm H$ is reconstructed via its charged two-body mesonic decay channel ($^{3}_{\Lambda}\mathrm{H} \rightarrow$ $^3$He + $\pi^-$ and the charge-conjugate process).

 Searching for an eco-friendly gas mixture for the ALICE Resistive Plate Chambers / ALICE Collaboration The ALICE RPCs are operated with a mixture of 89.7% $C_{2}H_{2}F_{4}$, 10% i-$C_{4}H_{10}$ and 0.3% $SF_{6}$. [...] arXiv:2209.02020. - Fulltext

 Neutron emission in ultraperipheral Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV / ALICE Collaboration, CERN /ALICE In ultraperipheral collisions (UPCs) of relativistic nuclei without overlap of nuclear densities, the two nuclei are excited by the Lorentz-contracted Coulomb fields of their collision partners. In these UPCs, the typical nuclear excitation energy is below a few tens of MeV, and a small number of nucleons are emitted in electromagnetic dissociation (EMD) of primary nuclei, in contrast to complete nuclear fragmentation in hadronic interactions.

 $R$-dependence of inclusive jet suppression and groomed jet splittings in heavy-ion collisions with ALICE / Bossi, Hannah (Yale U.) Jets in relativistic heavy-ion collisions (HICs) interact with the quark-gluon plasma (QGP), leading to effects such as a suppression of jet yields and a modification of internal jet structure that are used to measure the properties of the QGP.

 Performance of the ALICE Electromagnetic Calorimeter / ALICE Collaboration, CERN /ALICE The performance of the electromagnetic calorimeter of the ALICE experiment during operation in 2010$-$2018 at the Large Hadron Collider is presented. After a short introduction into the design, readout, and trigger capabilities of the detector, the procedures for data taking, reconstruction, and validation are explained [...] arXiv:2209.04216; CERN-EP-2022-184.- Geneva : CERN, 2022 - 129 p.

 Particle production as a function of underlying-event activity and very forward energy with ALICE / Fan, Feng (Hua-Zhong Normal U.) Measurements of charged-particle production in pp and p-Pb collisions at $\sqrt{s}_{\rm NN}=5.02$ TeV in the toward, away and transverse regions are discussed. [...] arXiv:2208.11348. - 4 p.

 Heavy-flavor jet properties and correlations from small to large systems with ALICE / Mazzilli, Marianna (CERN) The early production of heavy-flavor (HF, charm and beauty) quarks makes them an excellent probe of the dynamical evolution of quantum chromodynamics (QCD) systems.

 Open and hidden heavy-flavor production in small systems with ALICE / Perrin, Sebastien (IRFU, Saclay, DPHN) Measurements of quarkonia (heavy quark and antiquark bound states) and open-heavy flavour hadrons in hadronic collisions provide a unique testing ground for understanding quantum chromodynamics (QCD).

 Isolated photon-jet correlations in Pb-Pb collisions at $\sqrt{s_\text{NN}} = 5.02$ TeV in ALICE / Liu, Alwina (UC, Berkeley) Jets correlated with isolated photons are a promising channel to study jet quenching in heavy-ion collisions, as photons do not interact strongly and therefore constrain the $Q^2$ of the initial hard scattering.
