Jet substructure measurements elucidating partonic evolution in p+p collisions at RHIC

Ing. Monika Robotková
DHIP NPI

Jets are multiscale objects that connect partons to hadrons, making jet substructure measurements crucial for probing both perturbative and non-perturbative processes in QCD. At STAR, a variety of jet substructure observables, such as SoftDrop groomed splittings and N-Point Energy Correlators (ENC), provide insights into parton evolution and hadronization mechanisms. SoftDrop-groomed observables and ENCs both connect measurement to fundamental QCD at the parton level, allowing for comparisons to first principles theoretical calculations. Additionally, by also including charge information, as in the charge-weighted ENC, details about the hadronization mechanism can be obtained. In this talk, we present measurements of SoftDrop observables and ENCs across different jet momenta and radii in p+p collisions at √s = 200 GeV using STAR data.

Quarkonia and  Lorentz invariant picture of heavy (and light) quarks  confinement

Mgr. Vladimír Šauli, Ph.D.
DTP NPI

Though incomplete, a review of quarkonia and their transitions will be presented. The advantages and disadvantages of the theoretical tools used to describe them will be discussed. A nonperturbative method based on the functional formalism of quantum field theory will be compared with experiments and other methods. A picture of heavy quark confinement will be presented in the aforementioned framework.
