Spectroscopy of Orbitally Excited $$B_{s}$$ Mesons with the CDF II Detector
- Karlsruhe Inst. of Technology (KIT) (Germany)
The aim of particle physics is to understand the properties of matter on the most fundamental level. The two main questions are: ’What are the constituents of matter?’ and ’How do those constituents interact with one another?’ One approach used throughout the experimental testing of theories of matter, that aim to answer these questions, is the study of the energy spectrum of excited states. Especially in cases of simple configurations as found in the hydrogenium atom, the potential energy related to an interaction can be studied. In chapter 2 I describe basics of the Standard Model related to the study of orbitally excited mesons made of a b- and an s-quark [Bs], theoretical predictions, and results of previous experiments. In chapter 3 one can find a description of the experiment used to collect the data. In chapter 4 the important tools used in my analysis are explained. The following chapter 5 describes the first core of the analysis, the reconstruction and selection, before in chapter 6 the fits to the data, and the considered systematic uncertainties are presented.
