(2022) = Dissertation, GU Frankfurt, 2022 Das Feld der Hochenergie-Schwerionenforschung hat sich der Untersuchung des Quark-Gluon-Plasmas (QGP) gewidmet. Ein QGP ist ein sehr heißer und dichter Materiezustand, der kurz nach dem Urknall für einige Mikrosekunden das Universum füllte.

In this paper, the production of protons, deuterons and $^3$He and their charge conjugates at midrapidity is studied as a function of the charged-particle multiplicity in inelastic pp collisions at $\sqrt{s}=5.02$ TeV using the ALICE detector.

The measurements are performed as a function of the charm-hadron transverse momentum (p$_T$) in intervals of charged-particle multiplicity, measured with two multiplicity estimators covering different pseudorapidity regions. [...] 2023-01-1912:05 [GSI-2023-00210] Dataset ALICE Collaboration Investigating the role of strangeness in baryon$-$antibaryon annihilation at the LHC Annihilation dynamics plays a fundamental role in the baryon--antibaryon ($B-\overline{B}$) interaction at low-energy and its strength and range are crucial in the assessment of possible baryon bound states. Experimental data on annihilation cross sections are available for the $p-\overline{p}$ system but not in the low relative momentum region.

The study is also performed as a function of the charged-particle multiplicity, showing no modifications of the correlation function with multiplicity within uncertainties.

The largest contribution to $P_{\rm z}$ comes from elliptic flow induced vorticity and can be characterized by the second Fourier sine coefficient $P_{\rm z,\,{\rm s2}} = \langle{P_{\rm z}\sin(2\varphi - 2 \Psi_{\rm 2})}\rangle$, where $\varphi$ is the hyperon azimuthal emission angle, and $\Psi_{\rm 2}$ is the elliptic flow plane angle.

These observables are sensitive to momentum scales ranging from perturbative hard scatterings to nonperturbative fragmentation into final-state hadrons. [...] 2023-01-1911:52 [GSI-2023-00202] Dataset ALICE Collaboration Direct observation of the dead-cone effect in QCD In particle collider experiments, elementary particle interactions with large momentum transfer produce quarks and gluons (known as partons) whose evolution is governed by the strong force, as described by the theory of quantum chromodynamics (QCD). These partons subsequently emit further partons in a process that can be described as a parton shower which culminates in the formation of detectable hadrons.

The inclusive $\rm{J}/\psi$ mesons are reconstructed in the dielectron decay channel at midrapidity down to a transverse momentum $p_\mathrm{T}$ = 0. [...]
