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 $\eta$.

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.

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.

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. [...]

Hubert Curien, St. Etienne ; IUF, Paris) ; Johnson, Eliott Philippe (CERN) et al.
We present the progress related to CERN’s capacity of delivering highly penetrating, high-linear energy transfer (LET) heavy ions for radiation effect testing of electronic components within the CHARM High-energy Ions for Micro Electronics Reliability Assurance (CHIMERA) project. Profiting from the existing accelerator infrastructure, Monte Carlo simulations, and a 300- $\mu $ m-thick silicon diode, we highlight the beam characterization capabilities and a summary of the beam properties.

First measurement of symmetric cumulants of hexagonal flow harmonics in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV

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. [...]
