Investigating the p-$\pi^{\pm}$ and p-p-$\pi^{\pm}$ dynamics with femtoscopy in pp collisions at $\sqrt{s} = 13$ TeV / ALICE Collaboration, CERN /ALICE
The interaction between pions and nucleons plays a crucial role in hadron physics. It represents a fundamental building block of the low-energy QCD dynamics and is subject to several resonance excitations [...]

Measurement of $\omega$ meson production in pp and p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV / ALICE Collaboration, CERN
We present the measurement of the $p_{\rm T}$-differential production cross section of $\omega$ mesons in pp and p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV at midrapidity by ALICE. In addition, the first measurement of the nuclear modification factor $R_{\text{pPb}}$ for $\omega$ mesons at LHC energies is presented, complementing the existing measurements of lighter neutral mesons such as the $\pi^0$ and $\eta$. [...]

Observation of the $\Omega$(2012) baryon at the LHC / ALICE Collaboration, CERN
A signal consistent with the $\Omega$(2012) baryon has been observed with a significance of $15\sigma$ in pp collisions at $\sqrt{s} = 13$ TeV at the LHC. In this paper, the analysis technique is described and measurements of the mass and width of the $\Omega$(2012) are reported, along with the first measurement of its transverse-momentum spectrum and yield.

Measurement of isolated prompt photon production in pp and p–Pb collisions at the LHC / ALICE Collaboration, CERN
This paper presents the measurement of the isolated prompt photon inclusive production cross section in pp and p-Pb collisions by the ALICE Collaboration at the LHC. The measurement is performed in p-Pb collisions at centre-of-mass energies per nucleon pair of $\sqrt{s_{\text{NN}}}= 5.02$ TeV and $8.16$ TeV, as well as in pp collisions at $\sqrt{s} =5.02$ TeV and $8$ TeV.

Charged-particle multiplicity distributions over a wide pseudorapidity range in p-Pb collisions at $\sqrt{\textit{s}_{\rm NN}} = 5.02$ TeV / ALICE Collaboration, CERN
This paper presents the primary charged-particle multiplicity distributions in proton-lead collisions at a centre-of-mass energy per nucleon-nucleon collision of $\sqrt{\textit{s}}_{\rm NN} = 5.02$ TeV. The distributions are reported for non-single diffractive collisions in different pseudorapidity ranges. [...]

First measurement of symmetric cumulants of hexagonal flow harmonics in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV / Acharya, Shreyasi (INFN, Bari) ; 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.
Correlations between event-by-event fluctuations of anisotropic flow harmonics are measured in Pb-Pb collisions at a center-of-mass energy per nucleon pair of 5.02~TeV, as recorded by the ALICE detector at the LHC. This study presents correlations up to the hexagonal flow harmonic, $v_6$, which was measured for the first time. [...]

Light neutral-meson production in pp collisions at $\mathbf{\sqrt{s}}$ = 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.
The momentum-differential invariant cross~sections of ${\pi^{0}}$ and $\eta$ mesons are reported for pp collisions at $\sqrt{s} = 13$ TeV at midrapidity ($|y| < 0.8$). The measurement is performed in a broad transverse-momentum range of $0.2 < p_{\rm T} < 200$ GeV/$c$ and $0.4 < p_{\rm T} < 60$ GeV/$c$ for the ${\pi^{0}}$ and $\eta$, respectively, extending the $p_{\rm T}$ coverage of previous measurements.

Measurement of $\omega$ meson production in pp collisions at $\sqrt{s}$ = 13 TeV / Acharya, Shreyasi (Clermont-Ferrand U.) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; 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) et al.
The $p_{\rm T}$-differential cross section of $\omega$ meson production in pp collisions at $\sqrt{s}$ = 13 TeV at midrapidity ($|y| < 0.5$) was measured with the ALICE detector at the LHC, covering an unprecedented transverse-momentum range of $1.6 < p_{\rm T} < 50$ GeV/$c$. The meson is reconstructed via the $\omega \rightarrow \pi^+ \pi^- \pi^0$ decay channel. [...]

Studying charm hadronisation into baryons with azimuthal correlations of $\Lambda^+_{\rm c}$ with charged particles 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.
The distribution of angular correlations between prompt charm hadrons and primary charged particles in pp collisions is sensitive to the charm-quark hadronisation process. In this letter, charm-baryon correlations are measured for the first time by studying the azimuthal-angle difference between charged particles and prompt $\Lambda_{\rm c}^+$ baryons produced in pp collisions at a centre-of-mass energy $\sqrt{s} = 13$ TeV, with the ALICE detector.

Observation of partonic flow in proton–proton and proton–nucleus collisions / 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
Quantum Chromodynamics predicts a phase transition from ordinary hadronic matter to the quark–gluon plasma (QGP) at high temperatures and energy densities, where quarks and gluons (partons) are not confined within hadrons. The QGP is generated in ultrarelativistic heavy-ion collisions. [...]
