21. Radiative Corrections Beyond the Soft-Photon Approximation
Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : This thesis calculates the bremsstrahlung correction beyond the soft-photon approximation for the decay ω → π0 l+ l- . The effect of the radiative corrections on the extraction of the transition form factor from data is investigated. LÄS MER
22. Multiplicity and Classification of Final State Particles in Herwig7
Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : In this work we investigate the hard and soft interactions in the multiple parton interactions (MPI) simulation in Herwig7. The investigation covers how the number of soft and hard interactions in an event is linked to the multiplicity of final state particles. LÄS MER
23. Towards observing HH with ATLAS: ZH production and assessing theoretical uncertainties
Master-uppsats, KTH/FysikSammanfattning : Even though the Standard Model of particle physics represents one of the triumphs of modern physics and seems to predict the outcome of any collision experiment, it has several shortcomings and therefore needs to be extended. After the discovery of the Higgs boson, one of the main aims of experimental particle physics is to probe the Standard Model for measurements that deviate from predictions, as this would imply new physics.

24. Cosmological implications of a QCD-like composite Higgs model
Master-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationSammanfattning : Some of the shortcomings of the Standard Model of particle physics are the 'unnatural' value of the mass of the Higgs boson and the fact that the model cannot account for the process of baryogenesis - a mechanism which generates the observed asymmetry between matter and anti-matter in the Universe. The former is related to the fundamental scalar nature of the Higgs boson, connected to quadratic divergences in the mass corrections. LÄS MER
25. Looking for mono-Z signatures in Z-boson and scalar dark matter interactions
Kandidat-uppsats, Uppsala universitet/HögenergifysikSammanfattning : Even though there is a multitude of observational evidence from cosmology and astrophysics, the standard model does not include a suitable dark matter candidate and therefore physics beyond the standard model is necessary. There are hypotheses of what the particle candidate could be coming from theories such as supersymmetry or extra dimensions. LÄS MER
