75. LC wave function for nS vector meson states

Jan Čepila (CTU FNSPE)

9/20/24, 9:30 AM

The wave function entering the amplitude for vector meson production includes the part, where the dipole collapses into a vector meson. This process cannot be computed analytically, because of its non-perturbative character, so there are different models to describe this process. These models
are discussed in the presentation. The models are based on the solution of the Schrodinger equation...

76. Flow of heavy-flavor hadrons in small collisions systems using Run 3 data at the LHC

Alexian Marc Lejeune (Czech Technical University)

9/20/24, 10:10 AM

This talk will introduce flow measurements of heavy flavor hadrons in small systems with the goal of investigating the nature of collective phenomena. The presentation will present the procedure that will be used in an analysis that will be conducted on LHC run 3 data in proton-proton collisions. The latter will use the technique of the two particle correlations, using the newest addition to...

78. Central J/ψ in 2023 UPCs

Sára Haidlová

9/20/24, 10:30 AM

This talk presents one of the first results on the measurements of the J/psi vector meson in the central barrel of ALICE. The presented analysis was done on 30 runs of the 2023 Pb-Pb data-taking period with reconstructed apass2. The results show a need for stricter cut setting and cut analysis for skimmed datasets. Furthermore, it contains one of the first results on the measurements of J/psi...

79. Forward J/ψ in UPCs 2023

Diana Mária Krupová

9/20/24, 11:10 AM

This presentation will cover the analysis of forward J/psi photoproduction in ultra-peripheral collisions (UPCs) using Pb-Pb data from ALICE 2023 heavy-ion run. The talk will outline the process of calculating the cross section for the coherent J/psi, and the calculation of each of its components, performed using the O2Physics framework and Hyperloop. Several open items that could further...

80. Central ρ in 2023 UPCs

Jakub Juračka (FNSPE CTU)

9/20/24, 11:30 AM

This talk will present preliminary results of an ongoing analysis of central $\rho^0$ photoproduction in Pb--Pb UPCs from the 2023 $\sqrt{s_\mathrm{NN}}=5.36$~TeV LHC heavy-ion run. The presentation will introduce the utilised event selections, methods for event tagging into neutron classes based on information from the ZDC detectors, combinatorial background subtraction, and lastly the first...
