By Simon Spannagel

This thesis addresses varied issues, either very important for enforcing sleek high-energy physics experiments: detector improvement and information research. offering a concise advent to either the normal version of particle physics and the fundamental rules of semiconductor monitoring detectors, it provides the 1st size of the pinnacle quark pole mass from the differential cross-section of tt+J occasions within the dileptonic tt decay channel.

The first half makes a speciality of the improvement and characterization of silicon pixel detectors. To account for the anticipated raise in luminosity of the big Hadron Collider (LHC), the pixel detector of the compact muon solenoid (CMS) scan is changed by means of an upgraded detector with new front-end electronics. It provides accomplished try out beam experiences performed to make sure the layout and quantify the functionality of the hot front-end when it comes to monitoring potency and spatial solution. moreover, it proposes a brand new cluster interpol

ation technique, which makes use of the 3rd crucial second of the cluster cost distribution to enhance the location resolution.

The moment a part of the thesis introduces another size of the head quark mass from the normalized differential creation cross-sections of dileptonic best quark pair occasions with an extra jet. The power dimension is 8TeV. utilizing theoretical predictions at next-to-leading order in perturbative Quantum Chromodynamics (QCD), the head quark pole mass is set utilizing a template healthy method.
