  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. 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

  3. 3. 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

  4. 4. 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.

  5. 5. 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
