  1. 1. Quark Distributions and Charged Higgs Boson Production : Studies of Proton Structure and New Physics

    Författare :Johan Alwall; Gunnar Ingelman; Johan Rathsman; Dieter Zeppenfeld; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; quark distributions; parton density functions; proton structure; strange quark; intrinsic charm; charged Higgs boson; supersymmetry; NuTeV; LHC; parton showers; matrix element; elementary particle physics; Fysik; Physics; Fysik;

    Sammanfattning : The Standard Model describes all elementary particles known today, but at larger energies it will have to be complemented with new particles and interactions. To be able to distinguish new physics at proton colliders such as LHC at CERN, it is essential to have an appropriate description of the colliding protons and their interactions. LÄS MER

  4. 3. Charged Higgs Bosons at the ATLAS Experiment and Beyond

    Författare :Elias Coniavitis; Richard Brenner; Tord Ekelöf; Johan Rathsman; Marco Battaglia; Uppsala universitet; []
    Nyckelord :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; Elementary particle physics; Elementarpartikelfysik; High Energy Physics; Högenergifysik;

    Sammanfattning : 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. LÄS MER

  5. 4. Phenomenology of new Neutral Vector Bosons and Parton Distributions from Hadronic Fluctuations

    Författare :Andreas Ekstedt; Gunnar Ingelman; Johan Rathsman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QCD; Higgs; Gauge Symmetry; Standard Model; BFKL; PDF; DIS; Beyond the Standard Model; Colliders; Phenomenology; Effective Potential; Anomaly; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : The Higgs particle was first predicted in 1964, and was discovered in the summer of 2012 at the Large Hadron Collider (LHC). This discovery was the latest in a long list of successful Standard Model predictions spanning the last fifty years. LÄS MER

  7. 5. Phenomenology of Charged Higgs Bosons and B-meson Decays

    Författare :David Eriksson; Johan Rathsman; Gunnar Ingelman; Fabio Maltoni; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supersymmetry; Beyond Standard Model; B-Physics; Charged Higgs Boson; LHC; QCD; Spin Correlations; CMSSM; NUHM; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : For more than 30 years the Standard Model has been the theoretical foundation for particle physics. The theory has been verified successfully by experimental tests. Its biggest shortcoming is the non-discovery of the Higgs boson,responsible for giving the other particles masses. LÄS MER
