Strong interaction between quarks and gluons in the standard model is described by Quantum Chromodynamics (QCD). The investigation of the phase diagram of QCD has been an active subject for many years. Especially, this research focuses on the transition between hadrons at low temperatures and the quark-gluon plasma (QGP) at high temperatures. For the study of the quark-gluon plasma, hard...

An enhancement of the baryon-to-meson ratio has been observed for the inclusive production of light-flavour particles at intermediate transverse momenta (2 GeV/c < pT < 6 GeV/c) in heavy-ion collisions when compared to the ratio measured in proton-proton (pp) collisions at both RHIC and LHC collision energies. This enhancement is commonly attributed to parton coalescence and recombination in a...

During the Long Shutdown 2, ALICE group developed a new analysis software capable to handle data from the newly designed detectors with continuous readout. The whole structure of an analysis software had to be changed to fit the requirements of the Run 3. The presentation is focused on the structure of O2 and the multiplicity analysis of Pb-Pb Run3 data.

Models for deuteron, light nuclei, distorted nuclei and heavy nuclei are presented using potentials suggested by Woods-Saxon and the fitting of analytic functions to the resulting thickness functions.

a quantum mechanical system. The tomographic method bypasses much of the
field-theoretic formalism to concentrate on what can be observed with experimental data, and how
to characterize the data. The method of quantum tomography uses a known “probe” to explore an unknown system. Data

Probing of hadron structure and their properties is of great interest in studies of heavy-ion physics. One of the tools for said study is analysis of exclusive photoproduction of J/psi in ultra-peripheral collisions. Presented analysis shows a new perspective on studies of heavy-ion collisions using quantum tomography, a procedure independent of models focusing solely on measured observables....

Interference effects on the diffractive coherent photoproduction of the rho0 vector meson are studied at midrapidity with the ALICE detector. Interference comes about because there are two potential photon sources in Pb+Pb ultraperipheral collisions. The interference effects are expected to be more important at midrapidity, where both amplitudes are similar and at small impact parameters. In...

Ultra-peripheral collisions present an opportunity to study long-range interactions between heavy ions. A frequently studied process is vector meson photoproduction, which gives insight into low-$x$ phenomena such as gluon shadowing or saturation. Collisions of a new ion species would improve our understanding of the nucleon number dependence of photoproduction cross sections. A short LHC...

The structure of hadrons when probed at high energies, corresponding to small values of Bjorken-$x$, is an open problem. This talk will present the first measurement of the dependence of the incoherent photoproduction of J/$\psi$ off a lead ion on Mandelstam-$t$. The measurement was performed with the ALICE detector at midrapidity, $|y| < 0.8$, and the cross section was evaluated in five...

The structure of nucleons is one of the most important topics for a complete physical description of the fundamental nature of matter. Measurements of deep-inelastic scattering (DIS) carried out at HERA provide an outstanding set of results concerning the structure of protons. The results show that the density of gluons rise steeply for low Bjorken-$x$ values. The number of gluons grows with...

The ALICE Collaboration is divided into several working groups. The group, which is focusing on physics analysis of the UPC events, is called PAG-UPC and is successfully investigating the ALICE data for over a decade. In this talk, the current plans of the group for the analyses of the newest Run 3 data will be introduced.
