1. Spectroscopy of Stable and Radioactive Negative Ions
Abstract : Negative ions are unique quantum systems which are of fundamental interest within the field of atomic physics due to the importance of the electron correlation in their creation, stability, and existence. Properties of these ions, such as the electron affinity, i.e. READ MORE

2. Neutrino Oscillations and Charged Higgs Bosons – Experimental Projects for Physics beyond the Standard Model
Abstract : This thesis is based on work done in two different experimental projects. The first project, the Tau RICH, is a previously proposed τ-neutrino appearance experiment for the CERN neutrino beam at the Gran Sasso laboratory in Italy. The proposed experimental concept is based on the use of focusing RICH detectors with liquid radiator (C6F14). READ MORE

3. Looking for the Charged Higgs Boson : Simulation Studies for the ATLAS Experiment
Abstract : The discovery of a charged Higgs boson (H+) would be an unambiguous sign of physics beyond the Standard Model. This thesis describes preparations for the H+ search with the ATLAS experiment at the Large Hadron Collider at CERN. The H+ discovery potential is evaluated, and tools for H+ searches are developed and refined. READ MORE

4. First Determination of the Electric Charge of the Top Quark and Studies of the Top Quark Pair Background to New Physics
Abstract : This thesis is concerned with experimental investigations of properties of the top quark and processes involving this particle. In the first part of the thesis, the first determination of the electric charge of the top quark is presented. READ MORE

5. Spectroscopic studies of the negative state of atoms
Abstract : Negative ions are of fundamental interest in atomic physics due to the enhanced importance of the electron correlation. In this thesis new spectroscopic methods have been developed and then applied to study the nature of atomic negative ions. READ MORE
