A kidolgozandó feladat címe: The origin of collectivity in small systems via heavy-flavor measurements at the ALICE LHC experiment
A téma rövid leírása, a megoldandó legfontosabb feladatok felsorolása:

One of the greatest surprises of early CERN Large Hadron Collider (LHC) operation was the emergence of long-range multiparticle correlations ("flow") in small collision systems with high multiplicity. Whether such collective behavior may be attributed to the presence of the Quark-Gluon Plasma in small systems is still an open question. Recent studies, however, show that the emerging flow patterns may be understood with vacuum Quantum-Chromodynamics (QCD) effects. Probes with heavy quarks with respect to the underlying event (UE) provide us with a unique opportunity to disentangle different QCD effects at the soft-hard boundary, and thus understand the origin of flow in small collision systems.
The Run-II data taking period at LHC brought increased luminosity and an upgraded ALICE detector system, which allows for an unprecedented precision in the measurement of heavy quarks. The primary task of the PhD candidate is to evaluate the UE-dependent heavy-flavor production in small colliding systems (pp, p-Pb) in the ALICE experiment. Charmed mesons can be used to determine the heavy-flavor yield, while the activity int the UE may be characterized by the relative transverse multiplicity (R_T). The candidate is also expected to contribute to the preparations of ALICE for the Run-III data taking period. The novelty of the field will require development and application of new methods, however, it will also bring attention to the results within the scientific community.
