  1. 1. Phenomenology of Higgs Bosons Beyond the Standard Model

    University dissertation from Uppsala : Uppsala universitet

    Author : Glenn Wouda; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Particle physics; The Standard Model; Higgs bosons; Higgs mechanism; Beyond the Standard Model; Two Higgs Doublet Models; Charged Higgs boson; Higgs decays; Supersymmetry; Renormalization; LHC; Collider constraints; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : After a long history of searches, a Higgs boson H was discovered by the ATLAS and the CMS experiments at the Large Hadron Collider (LHC) in 2012. Its properties fit well the ones predicted by the Standard Model (SM) of particle physics. However, the SM can not explain other established properties of Nature, such as the existence of Dark Matter. READ MORE

  2. 2. Looking for the Charged Higgs Boson Simulation Studies for the ATLAS Experiment

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Martin Flechl; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; charged Higgs; tau; ATLAS; HEP; CERN; LHC; Particle Physics; Grid; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; högenergifysik; High Energy Physics;

    Abstract : 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. READ MORE

  3. 3. Quark Distributions and Charged Higgs Boson Production Studies of Proton Structure and New Physics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johan Alwall; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; quark distributions; parton density functions; proton structure; strange quark; intrinsic charm; charged Higgs boson; supersymmetry; NuTeV; LHC; parton showers; matrix element; elementary particle physics; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : The Standard Model describes all elementary particles known today, but at larger energies it will have to be complemented with new particles and interactions. To be able to distinguish new physics at proton colliders such as LHC at CERN, it is essential to have an appropriate description of the colliding protons and their interactions. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Henrik Öhman; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LHC; ATLAS; Higgs; Charged Higgs; Tau lepton; 2HDM; MSSM; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : 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. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Elias Coniavitis; Uppsala universitet.; [2010]
    Keywords : 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; NATURAL SCIENCES Physics Elementary particle physics; NATURVETENSKAP Fysik Elementarpartikelfysik; High Energy Physics; Högenergifysik;

    Abstract : 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. READ MORE
