  2. 1. Sensitivity and Uncertainty Analysis of Boiling Water Reactor Stability Simulations

    Author : Ivan Gajev; Weimin Ma; Tomasz Kozlowski; Kostadin Ivanov; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BWR Stability; Sensitivity; Uncertainty; SRA - Energy; SRA - Energi;

    Abstract : 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. READ MORE

  4. 2. Top Quarks at the Tevatron : Measurements of the Top Quark Production and Decay with the D0 Experiment

    Author : Jonas Strandberg; Barbro Åsman; Michael Albrow; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; elementary particle physics; D0; Tevatron; top quark; Physics; Fysik;

    Abstract : 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. READ MORE

  5. 3. The decay of beauty quark to τ lepton and neutrino in the DELPHI experiment at LEP

    Author : Gian Claudio Zucchelli; J.D. Hansen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; fysik;

    Abstract : 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. READ MORE

  6. 4. Meson production in pd collisions

    Author : Karin Schönning; Jozef Zlomanczuk; Bo Höistad; Susan Schadmand; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; meson production; measured angular distribution; total cross section; polarisation; Nuclear physics; Kärnfysik; Nuclear Physics; kärnfysik;

    Abstract : 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. READ MORE

  7. 5. 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

    Author : Petar Bokan; Arnaud Ferrari; Stan Lai; Richard Brenner; Markus Klute; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Higgs boson pair production; ATLAS; LHC; HL-LHC; particle physics; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : 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. READ MORE
