1. 1. 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

3. 2. Hunting the Charged Higgs Boson with Lepton Signatures in the ATLAS Experiment

   Författare :Alexander Madsen; Arnaud Ferrari; Johann Collot; Ellert Mattias; Albert de Roeck; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; charged Higgs boson; ATLAS; LHC; 2HDM; MSSM; particle physics; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : This thesis presents searches for a charged Higgs boson (H±) in proton-proton collisions with center-of-mass energies of 7 TeV and 8 TeV, using data collected by the ATLAS experiment at the Large Hadron Collider at CERN. Multiple search channels are used with the common characteristic of at least one charged lepton (electron or muon) that effectively reduces the multi-jet background and is used for efficient triggering.

4. 3. Searches for a Charged Higgs Boson in ATLAS and Development of Novel Technology for Future Particle Detector Systems

   Författare :Daniel Pelikan; Richard Brenner; Arnaud Ferrari; Elin Bergeås Kuutmann; Fabrizio Palla; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Charged Higgs boson; Matrix Method; ATLAS; 60 GHz; future particle detector; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : The discovery of a charged Higgs boson (H±) would be a clear indication for physics beyond the Standard Model. This thesis describes searches for charged Higgs bosons with the ATLAS experiment at CERN’s Large Hadron Collider (LHC). The first data collected during the LHC Run 1 is analysed, searching for a light charged Higgs boson (mH±.. LÄS MER

5. 4. Searches for Higgs bosons with hadronically decaying τ-leptons : Using Grid and Cloud computing techniques

   Författare :Henrik Öhman; Arnaud Ferrari; Paula Eerola; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LHC; ATLAS; Higgs; Charged Higgs; Tau lepton; 2HDM; MSSM; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : This thesis describes a measurement of the Standard Model Higgs boson coupling to fermions in decays to two τ-leptons, a search for charged Higgs bosons in decays to a τ-lepton and a neutrino, as well as the reconstruction, identification and triggering of hadronically decaying τ-leptons. The data considered are collected by the ATLAS experiment at the Large Hadron Collider. LÄS MER
