1. Searches for Particle Dark Matter : Dark stars, dark galaxies, dark halos and global supersymmetric fits
Sammanfattning : The identity of dark matter is one of the key outstanding problems in both particle and astrophysics. In this thesis, I describe a number of complementary searches for particle dark matter. LÄS MER
Sammanfattning : While the dark matter has so far only revealed itself through the gravitational inﬂuence it exerts on its surroundings, there are good reasons to believe it is made up by WIMPs – a hypothetical class of heavy elementary particles not encompassed by the Standard Model of particle physics. The Inert Doublet Model constitutes a simple extension of the Standard Model Higgs sector. LÄS MER
3. First Determination of the Electric Charge of the Top Quark and Studies of the Top Quark Pair Background to New Physics
Sammanfattning : 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. LÄS MER
