1. 1. Measurements of Angular Correlations in Minimum Bias Events and Preparatory Studies for Charged Higgs Boson Searches at the Tevatron and the LHC

   Författare :Camille Bélanger-Champagne; Claus Buszello; Tord Ekelöf; Nick van Remortel; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATLAS; D0; LHC; Tevatron; CERN; Fermilab; QCD; Monte Carlo tunes; Matrix Element method; Charged Higgs boson; Tau lepton; Trigger; Physics; Fysik; Elementary particle physics; Elementarpartikelfysik; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : Studies of minimum bias events at colliders probe the behavior of QCD in the non-perturbative regime. The phenomenology of events in this regime is described by empirical models that take many parameters, which all need to be tuned to the observed data. LÄS MER

3. 2. Searches for the Charged Higgs at Hadron Colliders Based on the Tau Lepton Signature

   Författare :Yann Coadou; Tord Ekelöf; William Trischuk; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; Elementarpartikelfysik; Elementary particle physics; Elementarpartikelfysik;

   Sammanfattning : The Standard Model of particle physics has been very successful in predicting a wide range of phenomena and has so far been confirmed by all existing data to a very high precision.The work described in this thesis tests the limits of validity of the Standard Model (SM) in two areas believed to be sensitive to deviations from the theory: the observation of unpredicted particles and CP violation.

4. 3. 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

5. 4. Emittance preservation and luminosity tuning in future linear colliders

   Författare :Peder Eliasson; Tord Ekelöf; Grahame Blair; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; linear colliders; CLIC; ILC; emittance preservation; luminosity tuning; beam-based alignment; dispersion free steering; tuning bumps; trajectory feedback; static imperfections; dynamic imperfections; jitter; ground motion; ATL model; multi-pulse emittance; curved tunnel; Elementary particle physics; Elementarpartikelfysik;

   Sammanfattning : The future International Linear Collider (ILC) and Compact Linear Collider (CLIC) are intended for precision measurements of phenomena discovered at the Large Hadron Collider (LHC) and also for the discovery of new physics. In order to offer optimal conditions for such experiments, the new colliders must produce very-high-luminosity collisions at energies in the TeV regime. LÄS MER

7. 5. Looking for the Charged Higgs Boson : Simulation Studies for the ATLAS Experiment

   Författare :Martin Flechl; Tord Ekelöf; Richard Brenner; Kinnunen Ritva; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; charged Higgs; tau; ATLAS; HEP; CERN; LHC; Particle Physics; Grid; Physics; Fysik; högenergifysik; High Energy Physics;

   Sammanfattning : The discovery of a charged Higgs boson (H+) would be an unambiguous sign of physics beyond the Standard Model. This thesis describes preparations for the H+ search with the ATLAS experiment at the Large Hadron Collider at CERN. The H+ discovery potential is evaluated, and tools for H+ searches are developed and refined. LÄS MER
