1. Sensitivity and Uncertainty Analysis of Boiling Water Reactor Stability Simulations
Sammanfattning : The best estimate codes are used for licensing of Nuclear Power Plants (NPP), but with conservative assumptions. It is claimed that the uncertainties are covered by the conservatism of the calculation. LÄS MER
2. Top Quarks at the Tevatron : Measurements of the Top Quark Production and Decay with the D0 Experiment
Sammanfattning : This thesis presents two measurements of the top quark using 230 pb-1 of data taken with the D0 detector at the Tevatron accelerator. The first measurement determines the top pair production cross section at sqrt(s)=1.96 TeV in proton-antiproton collisions. LÄS MER
3. The decay of beauty quark to τ lepton and neutrino in the DELPHI experiment at LEP
Sammanfattning : Using 3.5 millions hadronic Z0 events collected during the LEP1 period at the DELPHI detector, the decays of b quarks to tvt have been searched for in both the inclusive and exclusive decay modes. The analysis technique is based on b-tagging, missing energy and identifications of t products. LÄS MER
4. Pair production of Higgs bosons in the final state with bottom quarks and τ leptons in the ATLAS experiment : Search results using LHC Run 2 data and prospect studies at the HL-LHC
Sammanfattning : After the discovery of the Higgs boson, the ultimate test of the electroweak symmetry breaking and the Standard Model (SM) of particle physics is to establish evidence of Higgs boson self-coupling, which can be achieved by searching for pair production of Higgs bosons. In addition, many theories beyond the SM predict heavy resonances that could decay into pairs of Higgs bosons. LÄS MER
5. Meson production in pd collisions
Sammanfattning : Meson production in proton-deuteron collisions has been studied using the WASA detector facility at the CELSIUS storage ring in Uppsala. Data were obtained at two different beam energies, 1360 MeV and 1450 MeV, slightly above threshold for η and ω mesons. LÄS MER
