Charmed mesons serve as an excellent probe in the strongly interacting medium created during heavy ion collisions. This medium is called the quark-gluon plasma and it is an object of great interest due to its connection to the early stages of the Universe. The charmed mesons, such as the D$^\pm$, are created during the hard scattering part of the collision and therefore experience the entire...
One of the open questions in QCD today is the cause of the shadowing phenomenon
in nuclei. To understand this phenomenon it is necessary to study gluon distributions in
nuclei at small x. There are several models trying to describe such phenomenon in QCD
which have to be experimentally scrutinised and confirmed. One of the suitable processes
to investigate gluon distributions in nuclei is the...
Rydbergovské atomy jsou takové atomy, jejichž alespoň jeden elektron je excitován do vysokého kvantového stavu. Jejich doba života je extrémně dlouhá a vzhledem k tomu, že mají velký dipólový moment, jsou extrémně citlivé na působení externího pole, což se využívá především při manipulaci v takových polích. Experiment AEgIS, jemuž se věnuje první část práce, se v současné době zabývá výrobou...
