First measurement of jet angularities with D$^0$-meson tagged jets with ALICE / Dhankher, Preeti (UC, Berkeley) /ALICE Collaboration
The properties of partonic fragmentation in QCD are dependent on the flavours of the partons involved in the 1$\rightarrow$2 splitting processes underpinning parton showers. These flavour dependencies arise due both to the different Casimir factors of quarks and gluons, as well as the mass of heavy quarks. [...]

Observation of medium-induced yield enhancement and acoplanarity broadening of low-$p_{T}$ jets in pp and Pb-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV with ALICE / Hou, Yongzhen (CCNU, Wuhan, Inst. Part. Phys. ; Strasbourg, IPHC) /ALICE Collaboration
We present the measurements of the semi-inclusive distributions of charged-particle jets recoiling from a trigger hadron in proton–proton (pp) and 0–10% Pb–Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV, searching for medium-induced yield enhancement and acoplanarity broadening effects in low transverse momentum ($p_{\rm T}$) jets. This technique provides precise data-driven subtraction of the large uncorrelated background yield in jet measurements, enabling the measurement of recoil jet distributions to the large jet radius at low $p_{\rm T}$ in central Pb--Pb collisions.

Studying the dynamics of particle-emitting sources in p–Pb and Pb–Pb collisions with ALICE at the LHC energies using femtoscopy / Romanenko, Gleb (Bologna U.) ; Tomassini, Sofia (Bologna U.) /ALICE Collaboration
Space–time properties of the quark–gluon plasma (QGP), a state of matter with unbound partons usually produced in heavy-ion collisions, can be studied using femtoscopic correlations of particle pairs emitted after the hadronization.In this talk, results of 1D and 3D femtoscopic analyses of identical charged kaon pairs are reported in p–Pb and Pb–Pb collisions at \( \sqrt{s_{\textrm{NN}}} = 5.02 \, \text{TeV} \) as carried out by ALICE. The multiplicity dependence of 1D radii, compared to other collision systems at different energies, disfavors models suggesting similar evolution for matter created in small and large collision systems.

Measurement of the deuteron coalescence probability in jets with ALICE / Rasà, Marika (Catania U.) /ALICE Collaboration
The microscopic production mechanism of light (anti)nuclei in high-energy hadronic collisions is still mysterious and is a highly debated topic in the scientific community. Two different phenomenological models are typically used to describe the experimental data: the statistical hadronization model and baryon coalescence. [...]

J/𝜓 production and polarization in photon-induced reactions in Pb--Pb collisions with ALICE / Lavicka, Roman (OAW, Vienna) /ALICE Collaboration
Intense electromagnetic fields from ultrarelativistic heavy ions can trigger photonuclear reactions, which are used to probe the nuclear gluon distribution and gluonic fluctuations over a large range of Bjorken-$x$. Our study examines ultra-peripheral and nuclear-overlap collisions, reporting on the photoproduction of J/$\psi$ in peripheral Pb$-$Pb collision. [...]

Thermal radiation and direct photon production in Pb–Pb and pp collisions with dielectrons / Bailhache, Raphaelle (Frankfurt U.) /ALICE Collaboration
Electromagnetic probes such as photons and dielectrons (${\rm e^{+}e^{-}}$ pairs) are a unique tool to study the space-time evolution of the hot and dense matter created in ultrarelativistic heavy-ion collisions. At low dielectron invariant mass ($m_{\rm ee}$), thermal radiation from the hot hadronic phase contributes to the dielectron spectrum via decays of $\rho$ mesons, whose spectral function is sensitive to chiral-symmetry restoration.

Electroweak-boson measurements from small to large collision systems with ALICE at the LHC / Sakai, Shingo (Tsukuba U.) /ALICE Collaboration
Electroweak bosons, W$^{\pm}$ and Z$^{0}$, are massive weakly-interacting particles insensitive to the strong interaction. Therefore, they are unique probes in pp and heavy-ion collisions and provide a medium-blind probe of the initial state of the heavy-ion collision.In the ALICE experiment, the productions of W$^{\pm}$ and Z$^{0}$ are studied by exploiting their leptonic decay channels in a wide rapidity region.

These include the recently published inclusive J/$\psi$ yield and nuclear modification factor ($R_{\rm AA}$) at midrapidity and forward rapidity, as well as preliminary measurements of prompt and non-prompt J/$\psi$ $R_{\rm AA}$ at midrapidity.

Looking for collective origin of strangeness enhancement in small collision systems with ALICE at the LHC / Ahuja, Ishaan (Unlisted, SK) /ALICE Collaboration
The main goal of the ALICE experiment is to study the physics of strongly interacting matter, including the properties of the quark$-$gluon plasma (QGP). The increase in relative production of strange hadrons with respect to non-strange hadrons as a function of multiplicity is historically considered as one of the signatures of QGP formation during the evolution of the system created in heavy-ion collisions.
