1. 1. Investigation of 234U(n,f) with a Frisch-grid ionization chamber

   Författare :Ali Al-Adili; Franz-Josef Hambsch; Stephan Pomp; Richard Brenner; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : This work treats three topics. The main topic concerns neutron-induced fission of 234U. The main goal is to investigate the fission-fragments properties  as a function of the incident neutron energy. The study was carried out using a twin Frisch-grid ionization chamber. LÄS MER

3. 2. X-ray Fluorescence Spectrometry for Environmental Applications

   Författare :Siwen An; Göran Thungström; Börje Norlin; Richard Brenner; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Heavy metal contamination in environmental applications is particularly important because of its potential impact on associated ecosystems and human health. At present, monitoring of heavy metals is usually done by taking and preparing samples for off-line laboratory measurements. LÄS MER

4. 3. Search for charged Higgs bosons with tau-lepton signatures at the ATLAS experiment of the Large Hadron Collider and development of novel semiconductor particle detectors

   Författare :Eleni Myrto Asimakopoulou; Richard Brenner; Arnaud Ferrar; Elin Bergeås Kuutmann; Paula Collins; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Experimental High Energy Physics (HEP) studies are discussed in the context of exotic particle searches and data analysis techniques and the development and production of suitable detectors. The main covered topics span the aforementioned areas and are primarily related to the ATLAS experiment at the Large Hadron Collider (LHC). LÄS MER

5. 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

   Författare :Petar Bokan; Arnaud Ferrari; Stan Lai; Richard Brenner; Markus Klute; Uppsala universitet; []
   Nyckelord :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;

   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

7. 5. Charged Higgs Bosons at the ATLAS Experiment and Beyond

   Författare :Elias Coniavitis; Richard Brenner; Tord Ekelöf; Johan Rathsman; Marco Battaglia; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; particle physics; Standard Model; beyond the Standard Model; supersymmetry; MSSM; Higgs physics; charged Higgs boson; LHC; ATLAS; ATLAS Semi-Conductor Tracker; SCT; tau lepton; Lorentz angle; CLIC; Elementary particle physics; Elementarpartikelfysik; High Energy Physics; Högenergifysik;

   Sammanfattning : In the ATLAS experiment at the Large Hadron Collider (LHC) at CERN, direct searches for the elusive Higgs boson will be conducted, as well as for physics beyond the Standard Model. The charged Higgs boson (H±) is interesting both as a part of the Higgs sector, and as a clear sign of new physics. LÄS MER
