2. 1. Phenomenology of Higgs Bosons Beyond the Standard Model

   Author : Glenn Wouda; Rikard Enberg; Gunnar Ingelman; Johan Rathsman; Rui Santos; Uppsala universitet; []
   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

4. 2. Measurements of the Standard Model Higgs boson cross sections in the WW* decay mode with the ATLAS experiment

   Author : P. Edvin Sidebo; Jonas Strandberg; Markus Klute; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; p p: colliding beams; Higgs particle: hadroproduction; Higgs particle: decay; cross section: measured; High energy physics: experimental; Timing detectors; p p: scattering; ATLAS; Cern LHC Coll; Fysik; Physics;

   Abstract : This thesis summarises measurements of the Standard Model Higgs boson production cross sections based on proton–proton collision data at √s = 13 TeV produced by the Large Hadron Collider at CERN. By analysing data collected during 2015 and 2016 by the ATLAS experiment, corresponding to an integrated luminosity of 36 fb−1, the Higgs boson gluon–gluon fusion and vector boson fusion production cross sections are measured in the WW* decay mode.

5. 3. Physics at the High-Energy Frontier : Phenomenological Studies of Charged Higgs Bosons and Cosmic Neutrino Detection

   Author : Oscar Stål; Gunnar Ingelman; Johan Rathsman; Jonathan Ellis; Uppsala universitet; []
   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; Elementary particle physics; 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

6. 4. 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

7. 5. Top-Quark and Charged Higgs Boson Production at Hadron Colliders : Data Analysis at the DØ Experiment and Simulations for the ATLAS Detector

   Author : Nils Gollub; Tord Ekelöf; Richard Brenner; Patrizia Azzi; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; ATLAS; LHC; charged Higgs boson; MSSM; D0; Tevatron; top quark; elementary particle physics; Elementarpartikelfysik; Elementary particle physics; Elementarpartikelfysik;

   Abstract : This thesis treats two different projects, both aiming at experimental tests at hadron colliders of some specific predictions of the Standard Model (SM) of particle physics and of its Minimal Supersymmetric extension (MSSM). The thesis is based on four papers. READ MORE
