  2. 6. Search for beyond Standard Model physics with high-pT leptons

    Author : Oleksandr Viazlo; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LHC; ATLAS; TRT; LUCID; Luminosity; Beyond Standard Model; Doubly Charged Higgs; Fysicumarkivet A:2017:Viazlo;

    Abstract : This thesis covers four different topics related to the physics analysis in the ATLAS experiment that uses proton-proton collisions data provided by the Large Hadron Collider. The first topic is focused on the numerical simulation of the Transition Radiation Tracker which is one of the ATLAS tracking detectors. READ MORE

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

    Author : Martin Flechl; Tord Ekelöf; Richard Brenner; Kinnunen Ritva; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; charged Higgs; tau; ATLAS; HEP; CERN; LHC; Particle Physics; Grid; Physics; 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

  5. 8. Search for Charginos and Sleptons in ATLAS and Identification of Pile-up with the Tile Calorimeter

    Author : Pawel Klimek; Christophe Clément; Barbro Åsman; Freya Blekman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS experiment; particle physics; high energy physics; supersymmetry; SUSY; beyond standard model; chargino; neutralino; slepton; vector boson fusion; VBF; Tile calorimeter; TileCal; pile-up; quality factor; Large Hadron Collider; LHC; CERN; fysik; Physics;

    Abstract : The standard model of particle physics (SM) describes the elementary particles and their interactions. Supersymmetry (SUSY), a symmetry beyond those included in the standard model could resolve some of the SM shortcomings. It can provide a candidate for Dark Matter and a solution to the hierarchy problem. READ MORE

  6. 9. Studies of effective theories beyond the Standard Model

    Author : Stella Riad; Tommy Ohlsson; Mattias Blennow; Johan Rathsman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Effective field theories; neutrino physics; extra dimensions; universal extra dimensions; Higgs physics; renormalization group running; Bayesian statistics; coupling scale factor; grand unified theories;

    Abstract : The vast majority of all experimental results in particle physics can be described by the Standard Model (SM) of particle physics. However, neither the existence of neutrino masses nor the mixing in the leptonic sector, which have been observed, can be described within this model. READ MORE

  7. 10. Search for New Scalar Particles with ATLAS

    Author : Stefio Yosse Andrean; Christophe Clement; Sara Strandberg; Markus Klute; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Large Hadron Collider; ATLAS; Standard Model; Higgs; supersymmetry; calorimeter; Physics; fysik;

    Abstract : The Large Hadron Collider (LHC) is currently the most powerful particle accelerator ever built. It accelerates protons and collides them at the center of mass energy of √s = 13 TeV. READ MORE
