After its installation in the CMS experiment, the CMS silicon tracker has been commissioned,
calibrated and aligned based on several million reconstructed tracks, recorded during …

In this thesis, measurements of the production cross sections for top-quark pairs and the
determination of the top-quark mass are presented. Dileptonic decays of top-quark pairs (tt) …

Since centuries mankind tries to identify the basic constituents of matter and describe their
interaction. Although the understanding of the fundamental forces and particles is not yet …

The CMS all-silicon tracker consists of 16588 modules. Therefore its alignment procedures
require sophisticated algorithms. Advanced tools of computing, tracking and data analysis …

The trimuon signature appears in leptonic decays of charginos and neutralinos and
potentially has only a small SM background in comparison with other SUSY searches. This …

T he evolution of particle physics during the last century has radically changed our
understanding of nature and the universe. The Standard Model (SM) which is based on …

Fusion, in all its varieties, is a very current subject of science and technology. The results of
strongly exothermic reaction of thermonuclear fusion between nuclei of deuterium and …

After more than twenty years of development, collisions at the Large Hadron Collider at
CERN are expected to take place at the end of 2009. The aim of the CMS detector is to …

Abstract The CERN Large Hadron Collider (LHC) offers a unique opportunity to test the
Standard Model of particle physics. The Standard Model predicts the existence of a Higgs …

Ziel dieser Arbeit ist es gewesen, basierend auf simulierten Daten, das Potential der Top-
Massenbestimmung mit dem CMS-Detektor zu studieren. Dabei liegt im Fokus dieser Arbeit …
