1. Search for new Phenomena in Dijet Angular Distributions at √s = 8 and 13 TeV
Sammanfattning : A new energy regime has recently become accessible in collisions at the Large Hadron Collider at CERN. Abundant in hadron collisions, the two-jet final state explores the structure of the constituents of matter and the possible emergence of new forces of nature, in the largest momentum transfer collisions produced.

2. Investigation of Quark Gluon Plasma-like signals with Lund string interactions
Sammanfattning : This thesis investigates the interactions that occur in extreme densities for high-energy collisions of subatomic particles. The theoretical models developed for this purpose are based on the Lund model. The developments have been implemented as a new module called Gleipnir to the Monte-Carlo event generator, P YTHIA .

3. Hadronization Effects in the Strong Interaction
Sammanfattning : Different hadronization effects in high energy interactions are investigated. The frame-work is the Lund model for the strong interaction. A model for baryon production in jet fragmentation is presented and extended to baryon remnant fragmentation in deep inelastic scattering and hadron--hadron collisions. LÄS MER
4. Searches for new physics phenomena with jet final states in the ATLAS detector
Sammanfattning : Collimated sprays of paticle, known as jets,are abundantly produced in high-energy proton-proton (pp) collisions, and are predicted by many theories of physics beyond the Standard Model. This thesis reports first on the calibration of jets with focus on the data-driven in situ calibration. LÄS MER
5. Top-Quark and Charged Higgs Boson Production at Hadron Colliders : Data Analysis at the DØ Experiment and Simulations for the ATLAS Detector
Sammanfattning : This thesis treats two different projects, both aiming at experimental tests at hadron colliders of some specific predictions of the Standard Model (SM) of particle physics and of its Minimal Supersymmetric extension (MSSM). The thesis is based on four papers. LÄS MER
