2. 1. B-physics potential of the ATLAS experiment and performance of the ATLAS Transition Radiation Tracker

   Author : Chafik Driouichi; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS; B-physics; LHC; Bc meson; Elementary particle physics; Transition Radiation Tracker; quantum field theory; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2004:Driouichi;

   Abstract : The ATLAS experiment is one of the four experiments at the Large Hadron Collider (LHC), which is supposed to be operational in early 2007. Proton-proton collisions at an unprecedented center-of-mass energy of 14 TeV will probe new frontiers of the universe, hopefully providing a better understanding of the laws governing our universe.

4. 2. The search for a standard model Higgs at the LHC and electron identification using transition radiation in the ATLAS tracker

   Author : Ulrik Egede; Partikel- och kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; Elementary particle physics; tracker; Large Hadron Collider; pion rejection; pattern recognition; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:1998:Egede;

   Abstract : The Large Hadron Collider (LHC) will be ready for proton-proton collisions in the year 2005 and the ATLAS detector will be one of the two experiments at the LHC which will explore a new and higher energy range for particle physics. In this thesis, an analysis of the power of the ATLAS detector to detect a Standard Model Higgs boson has been performed. READ MORE

5. 3. Transition Radiation Tracker calibration, searches beyond the Standard Model and multiparticle correlations in ATLAS

   Author : Alejandro Alonso; Partikel- och kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Beyond Standard Model; ATLAS; LHC; Fourth family of quarks; Same-sign top production; Drift tubes; TRT; QCD; Supersymmetry; Inner Detector calibration; Tracking;

   Abstract : This thesis contains two different aspects of my research work towards physics in proton-proton collisions in the ATLAS experiment at the LHC. The first part is focused on the understanding and developing of a calibration system to obtain the best possible charged particle reconstruction in the Transition Radiation Tracker. READ MORE

6. 4. Search for Dark Matter in events with missing transverse momentum and a Higgs boson decaying into bottom quarks with the ATLAS detector

   Author : Eleni Skorda; Partikel- och kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS; LHC; Beyond the Standard Model; RECAST; Missing transverse momentum; Higgs boson; Bottom quarks; Transition Radiation Tracker; Dark Matter; Fysicumarkivet A:2022:Skorda;

   Abstract : Many astrophysical observations indicate the existence Dark Matter, which is not predicted by the Standard Model (SM) of particle physics. Many theories beyond the Standard Model (BSM) predict new heavy particles called WIMPs (Weakly Interacting Massive Particles). READ MORE

7. 5. Search for doubly charged Higgs bosons in multi-lepton final states with the ATLAS detector

   Author : Katja Mankinen; Partikel- och kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS; Beyond the Standard Model; Doubly Charged Higgs; Left-right symmetry; LHC; Same-charge leptons; Taus; Transition radiation tracker; Fysicumarkivet A:2020:Mankinen;

   Abstract : Standard Model events with prompt, isolated, same-charge high-pT leptons are rare, and therefore events with such final states provide a powerful signature towards new discoveries. This thesis presents two searches for doubly charged Higgs bosons decaying into same-charge lepton pairs using proton–proton collision data recorded by the ATLAS detector at the LHC. READ MORE
