Parallel 2: heavy quark production
- Roberta Arnaldi (Universita e INFN Torino (IT))
Recent research suggested that hot nuclear matter phenomena also occur in small systems in the charm sector. To deepen the understanding of the source of such phenomena, we will present the charm hadron production in pPb collisions, focusing on the $\Lambda_{c}$-to-$D^{0}$ ratio in different multiplicities to examine the hadronization mechanisms. The results are also compared to the light and...
In hadron-hadron collisions at LHC energies, Multiple Parton Interactions (MPI), where multiple hard-parton scatterings can occur in the same collision, play a significant role. Among MPI scenarios, Double-Parton Scatterings (DPS) represent the simplest case. The DPS contribution to a given process with two final-states A and B can be expressed as the product of the cross-sections of the...
Measurements of beauty-hadron production in ultrarelativistic hadronic collisions provide a fundamental tool for testing perturbative QCD calculations. Recent results at the LHC show that the beauty fragmentation function, as well as that of charm, is not universal across different collision systems. An extension of these studies to further energies, rapidities and collision systems has thus...
The novel fixed-target program pioneered by the LHCb experiment during
the LHC Run 2 has been upgraded for Run 3 with a dedicated gas injection system, SMOG2. Featuring an improved gas confinement to increase the fixed-target luminosity and a new system that allows the injection of non-noble gases, SMOG2 enables the collection of large samples of pA and PbA fixed-target collisions, including...
In hadronic collisions, charm and beauty quarks are mainly produced in hard partonic scatterings due to their large masses. Thus, they are ideal tools to investigate various aspects of perturbative QCD. In addition, measurements in pp collisions represent a baseline for cold nuclear matter studies in p-A collisions, and for the characterization of the hot and dense medium, the quark-gluon...
The measurement of open charm meson production provides a tool for the investigation of the properties of the hot and dense matter created in nucleus-nucleus collisions at relativistic energies. In particular, charm mesons are of vivid interest in the context of the study of the nature of the phase-transition between confined hadronic matter and the quark-gluon plasma. Recently, the...
