Investigating baryon-strangeness and charge-strangeness correlations in Pb$-$Pb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV with ALICE / Saha, Swati (NISER, Jatni ; HBNI, Mumbai)
To explore the quantum chromodynamics (QCD) phase transitions and the properties of quark$-$gluon plasma, the ALICE collaboration at CERN has conducted an extensive analysis of the correlations among net-conserved quantities, namely net-baryon, net-charge, and net-strangeness. [...]

Investigating charm quark energy loss in medium with the nuclear modification factor of D$^0$-tagged jets / ALICE Collaboration, CERN /ALICE
The nuclear modification factor $R_\mathrm{AA}$ of charm jets, identified by the presence of a D$^0$ meson among the jet constituents, has been measured for the first time in Pb-Pb collisions at a centre-of-mass energy per nucleon pair $\sqrt{s_{\rm NN}} = 5.02$ TeV with the ALICE detector at the LHC. The D$^0$ mesons and their charge conjugates are reconstructed from the hadronic decay D$^0\to \mathrm K^{-}\pi^{+}$. [...]

Measurement of f$_{1}$(1285) production in pp collisions at $\sqrt{s}$ = 13 TeV / ALICE Collaboration, CERN /ALICE
This study presents the first measurement of the f$_{1}$(1285) resonance using the ALICE detector in inelastic proton--proton collisions at a center-of-mass energy of 13 TeV. The resonance is reconstructed at midrapidity ($|y| <$ 0.5) through the hadronic decay channel f$_{1} (1285) \rightarrow \mathrm{K^{0}_{S} K^{\pm}\pi^{\mp}}$. [...]

First measurement of $\pmb{\mathrm{D_{s1}}(1^{+})(2536)^+}$ and $\pmb{\mathrm{D_{s2}^{*}(2^{+})(2573)^+}}$ production in proton--proton collisions at $\pmb{\sqrt{s} = 13}$ TeV at the LHC / ALICE Collaboration, CERN
The production yields of the orbitally excited charm-strange mesons $\mathrm{D_{s1}(1^{+})(2536)^+}$ and $\mathrm{D_{s2}^{*}(2^{+})(2573)^+}$ were measured for the first time in proton--proton (pp) collisions at a center-of-mass energy of $\sqrt{s} =13$ TeV with the ALICE experiment at the LHC. The $\mathrm{D_{s1}^+}$ and $\mathrm{D_{s2}^{*+}}$ mesons were measured at midrapidity ($|y|<0.5$) in minimum-bias and high-multiplicity pp collisions in the transverse-momentum interval $2 < p_{\rm T} < 24$ GeV/$c$.

Coherent J/$\psi$ photoproduction at midrapidity in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV / ALICE Collaboration, CERN
The coherent J/$\psi$ photoproduction cross section is measured for the first time at midrapidity in peripheral to semicentral Pb--Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV. The centrality differential cross section ${\rm d} \sigma/ {\rm d}y$ is reported for the centrality range 40--90\%, together with the doubly-differential cross section ${\rm d}^2 \sigma /{\rm d}y {\rm d} p_{\rm T}$, extracted in two peripheral centrality classes.

Multiplicity-dependent jet modification from di-hadron correlations in pp collisions at $\sqrt{s}=13$ TeV / Acharya, Shreyasi (Clermont-Ferrand U.) ; Agarwal, Apar (Calcutta, VECC) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Ahuja, Ishaan (Kosice U.) et al. /ALICE
Short-range correlations between charged particles are studied via two-particle angular correlations in pp collisions at $\sqrt{s}=13$ TeV. The correlation functions are measured as a function of the relative azimuthal angle $\Delta\varphi$ and the pseudorapidity separation $\Delta\eta$ for pairs of primary charged particles within the pseudorapidity interval $|\eta|<0.9$ and the transverse-momentum range $1<p_{\rm T}<8$ GeV/$c$.

Exploring nuclear structure with multiparticle azimuthal correlations at the LHC / Acharya, Shreyasi (Clermont-Ferrand U.) ; Agarwal, Apar (Calcutta, VECC) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Ahuja, Ishaan (Kosice U.) et al. /ALICE
Understanding nuclear structure provides essential insights into the properties of atomic nuclei. In this paper, details of the nuclear structure of ${\rm ^{129}Xe}$, such as the quadrupole deformation and the nuclear diffuseness, are studied by extensive measurements of anisotropic-flow-related observables in Xe--Xe collisions at a center-of-mass energy per nucleon pair $\sqrt{s_{\rm NN}}=5.44$ TeV with the ALICE detector at the LHC.
