16. Di-Higgs Production in the Standard Model and Beyond
Master-uppsats, Stockholms universitet/FysikumSammanfattning : This thesis examines how the kinetic properties of pair-produced Higgs bosons depend on whether the process is mediated by particles in the Standard Model or a simplified supersymmetric model. The analysis is based on simulated data made using MadGraph. LÄS MER
17. Using Artificial Neural Networks to optimize scattering probabilities
Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : Monte Carlo event generators are used by theoretical particle physicists to get a better understanding of the phenomena in particle physics. Given the improvements in precision and accuracy of event generators, using these tools can be very CPU intensive. LÄS MER
18. 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.

19. Resolving Quasi-Degenerate Higgs Bosons
Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : Many models beyond the Standard Model that predict the existence of multiple Higgs bosons. In general, some of these additional Higgs bosons could be quasi-degenerate in mass either to each other or to the observed 125 GeV Higgs boson. The goal of this thesis is to study under which circumstances we can resolve such Higgs bosons. LÄS MER
20. 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
