  1. 1. Physics at the High-Energy Frontier Phenomenological Studies of Charged Higgs Bosons and Cosmic Neutrino Detection

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Oscar Stål; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle physics; Standard Model; beyond the Standard Model; supersymmetry; Higgs physics; charged Higgs boson; LHC; flavour physics; ultra-high-energy neutrinos; Askaryan effect; radio detection; lunar satellites; NATURAL SCIENCES Physics Elementary particle physics; NATURVETENSKAP Fysik Elementarpartikelfysik; högenergifysik; High Energy Physics;

    Abstract : The Standard Model of particle physics successfully describes present collider data. Nevertheless, theoretical and cosmological results call for its extension. A softly broken supersymmetric completion around the TeV scale solves several of the outstanding issues. Supersymmetry requires two Higgs doublets, leading to five physical Higgs states. READ MORE

  2. 2. Search for beyond Standard Model physics with same-sign dileptons

    University dissertation from Department of Physics, Lund University

    Author : Anthony Hawkins; Lunds universitet.; Lund University.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Doubly Charge Higgs; Beyond Standard Model; LHC; ATLAS; TRT; Same-sign leptons; Fysicumarkivet A:2014:Hawkins;

    Abstract : Popular Abstract in Swedish Frågorna som partikelfysiker ställer är samma frågorna som folk har ställt under hela mänsklighetens tid på jorden, nämligen: Var kommer vi från? Vad är det som bygger upp det universum som vi ser? Hur håller allting ihop? Fysiker, historiens stora tänkare och hobbyfilosofen i pubben har alla funderat över de här frågorna (vissa mer än andra). Partikelfysiker försöker hitta svaret från perspektivet av universums minsta beståndsdelar, partiklar. READ MORE

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

    University dissertation from Lund University, Faculty of Science, Department of Physics

    Author : Oleksandr Viazlo; Lunds universitet.; Lund University.; [2017-01]
    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. 4. Calibration of the ATLAS calorimeters and discovery potential for massive top quark resonances at the LHC

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Elin Bergeås Kuutmann; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; particle physics; the ATLAS experiment; the Large Hadron Collider; calorimeter; calorimetry; hadronic calibration; top quark; top quark pair resonances; search for physics beyond the Standard Model; NATURAL SCIENCES Physics Elementary particle physics; NATURVETENSKAP Fysik Elementarpartikelfysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; fysik; Physics;

    Abstract : ATLAS is a multi-purpose detector which has recently started to take data at the LHC at CERN. This thesis describes the tests and calibrations of the central calorimeters of ATLAS and outlines a search for heavy top quark pair resonances. READ MORE

  5. 5. Exploring particle physics beyond the Standard Model

    University dissertation from Stockholm University

    Author : Sebastian Baum; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Abstract : The standard model of particle physics (SM) is arguably the best tested theory of physics, providing an accurate description of virtually all high energy particle physics phenomena observable in the laboratory. However, the SM also has a number of shortcomings: some of more theoretical nature such as the fine-tuning problem of the Higgs or the strong-CP problem, and some of more phenomenological nature such as not allowing for a satisfying implementation of neutrino masses and the lack of a suitable candidate for the observed dark matter of the Universe.
