  2. 1. Search for Charged Higgs Bosons in e+e− Collisions

    Author : Mattias Ellert; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Strålningsvetenskap; Radiation biology; Strålningsbiologi; High Energy Physics; Högenergifysik;

    Abstract : Several extensions to the Standard Model predict the existence of charged Higgs bosons. This thesis describes the search for such a particle using the data collected by the DELPHI detector at the Large Electron Positron (LEP) collider at the European laboratory for particle physics (CERN) in Geneva, Switzerland.

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

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

    Abstract : 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.
