  2. 11. 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

  4. 12. Phenomenology of Diffractive Higgs Production and Large Extra Dimensions

    Author : Malin Sjödahl; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ADD; black holes; gravitational scattering; quantum field theory; Elementary particle physics; LHC; cosmic rays; Kosmisk strålning; högenergi; High energy interactions; kvantfältteori; Elementarpartikelfysik; Higgs; large extra dimensions; Diffractive;

    Abstract : This thesis is based on phenomenological predictions for high energy particle collisions from two different theoretical models. The first two papers deal with uncertainties in exclusive reactions of type proton + proton -> proton + proton + Higgs. READ MORE

  5. 13. 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

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

    Author : Johan Alwall; Gunnar Ingelman; Johan Rathsman; Dieter Zeppenfeld; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 15. Soft resummation and hard evolution : Renormalization group methods in effective theories and multi scalar models

    Author : Joel Oredsson; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Higgs; Particle physics; two-Higgs-doublet model; Soft-Collinear-Effective Theory; Renormalization;

    Abstract : This thesis is composed out of five papers that deal with various problems intheoretical particle physics. While paper I is a precision calculation in aneffective theory of the Standard Model, paper II to V all deal with beyond theStandard Model physics. Paper IV is a manual for the tools developed during ourwork on paper II to V.Paper I. READ MORE
