Recent results on ultra-peripheral collisions with the ALICE experiment / Grund, David (Prague, Tech. U.)
Recent measurements of J/$\psi$ photoproduction based on data from ultra-peripheral Pb-Pb and p-Pb collisions recorded by the ALICE experiment during Run 2 of the LHC are presented. [...]

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. [...]
