  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. Phenomenological Studies on Supersymmetry and the Strong Force

    University dissertation from Peter Skands, Hökvägen 14, 227 32 Lund

    Author : Peter Skands; Lunds universitet.; Lund University.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; R-parity violation; Physics; beam remnants; hadronisation; parton showers; underlying event; Supersymmetry; Fysik; QCD; Fysicumarkivet A:2004:Skands;

    Abstract : In this thesis, we first consider the phenomenology of R-parity violating supersymmetric extensions of the Standard Model. Specifically, a large number of Lepton and Baryon Number violating decays of sparticles to particles are implemented in the Pythia event generator. READ MORE

  3. 3. Calibration of b-tagging and search for Dark Matter Calibration of b-tagging efficiency and search for Dark Matter production in association with heavy flavour quarks with the ATLAS experiment

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Anna Shcherbakova; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; physics analysis; LHC; Large Hadron Collider; Dark Matter; b-tagging; Physics; fysik;

    Abstract : The Large Hadron Collider (LHC) is the most powerful and complex particle accelerator ever built. The ATLAS and the CMS are the two multipurpose particle detectors at the LHC, designed to cover a wide range of physics measurements. READ MORE

  4. 4. Pion and Kaon Dynamics at Higher Orders in Chiral Perturbation Theory

    University dissertation from Department of Theoretical Physics, Lund University

    Author : Pierre Dhonte; Lunds universitet.; Lund University.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; chiral perturbation theory; strong interactions; pseudo-scalar mesons; Mathematical and general theoretical physics; form factors; scattering; classical mechanics; relativity; quantum mechanics; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2004:Dhonte;

    Abstract : Popular Abstract in Swedish Beräkningar av högre ordning i kiral störningsteorin med tre kvarkar presenteras. De relevanta frihetsgraderna i denna teorin är de lättaste pseudo-skalära mesonerna, pionen och kaonen. Syftet med dessa beräkningar är dubbelt. READ MORE

  5. 5. Renormalization in Effective Field Theory and Hidden Radiation

    University dissertation from Department of Astronomy and Theoretical Physics, Lund University

    Author : Lisa Carloni; Lunds universitet.; Lund University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Renormalization; Effective theories; Phenomenological Models; Hidden Sectors;

    Abstract : Popular Abstract in Swedish Denna avhandling handlar om modeller inom partikelfysik, vilka beskriver naturens minsta beståndsdelar. För att studera dessa små grundläggande byggstenar behöver man hög energi. Desto st ¨orre energi ju mindre avstånd kan man studera. READ MORE
