  1. 1. Exploration of extended Higgs sectors, development of a displaced track trigger, and improvements in GRID middleware

    Författare :Max Isacson; Elin Bergeås Kuutmann; Patrizia Azzi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; BSM; Supersymmetry; Standard Model; Higgs; 2HDM; Charged Higgs; Compositeness; Pattern Matching; GRID; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : Two possible solutions to the Standard Model (SM) fine-tuning problem are presented in this thesis, MSSM and Compositeness. The Higgs sector of the MSSM can be tested by searching for charged Higgs bosons. Two direct searches for charged Higgs bosons decaying into a top- and bottom-quark are performed using 13.2 and 36.

  3. 2. Search for new Phenomena in Dijet Angular Distributions at √s = 8 and 13 TeV

    Författare :Lene Bryngemark; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; LHC; quark compositeness; dark matter; pile-up; quantum black holes; Contact Interactions; 13 TeV; 8 TeV; beyond the Standard Model; angular distributions; dijets; Jets;

    Sammanfattning : A new energy regime has recently become accessible in collisions at the Large Hadron Collider at CERN. Abundant in hadron collisions, the two-jet final state explores the structure of the constituents of matter and the possible emergence of new forces of nature, in the largest momentum transfer collisions produced.

  4. 3. Searches for new phenomena in inclusive and tagged dijet distributions at √s = 13 TeV

    Författare :Trine Poulsen; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Dijets are produced in abundance at the Large Hadron Collider as predicted by quantum chromodynamics (QCD). However, several theories beyond the Standard Model of Particle Physics predicts new phenomena, which also result in dijet final states. This thesis presents searches for such new phenomena using different techniques. LÄS MER

  5. 4. Exotic phases of matter in compact stars

    Författare :Fredrik Sandin; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Fysik;

    Sammanfattning : This doctoral thesis in physics at Luleå University of Technology is devoted to the phenomenology of compact stars, and theoretical models of their interior. Particle physics has provided fundamental concepts and details needed to develop a description of matter and the evolution of the universe. LÄS MER
