2. 1. Particle Phenomenology of Compact Extra Dimensions

   Author : Henrik Melbéus; Tommy Ohlsson; Andrea Romanino; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Higher-dimensional quantum field theories; universal extra dimensions; Arkani-Hamed–Dimopolous–Dvali ADD model; hierarchy problem; Kaluza– Klein dark matter; neutrino mass; seesaw mechanism; leptonic mixing; renormalization group running; collider phenomenology; Large Hadron Collider;

   Abstract : This thesis is an investigation of the subject of extra dimensions in particle physics. In recent years, there has been a large interest in this subject. In particular, a number of models have been suggested that provide solutions to some of the problem with the current Standard Model of particle physics. READ MORE

4. 2. 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. 3. Astrophysical and Collider Signatures of Extra Dimensions

   Author : Henrik Melbéus; Tommy Ohlsson; Jörn Kersten; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extra-dimensional quantum field theories; universal extra dimensions; Kaluza-Klein dark matter; Arkani-Hamed-Dimopoulos-Dvali model; hierarchy problem; neutrino mass; seesaw mechanism; Large Hadron Collider phenomenology; Elementary particle physics; Elementarpartikelfysik;

   Abstract : In recent years, there has been a large interest in the subject of extra dimensions in particle physics. In particular, a number of models have been suggested which provide solutions to some of the problems with the current Standard Model of particle physics, and which could be tested in the next generation of high-energy experiments.

6. 4. Search for Supersymmetry and Large Extra Dimensions with the ATLAS Experiment

   Author : Gabriele Bertoli; Christophe Clement; Martijn Mulders; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS; CERN; large extra dimensions; supersymmetry; compressed; squark; neutralino; monojet; ADD; standard model; fysik; Physics;

   Abstract : The Large Hadron Collider is the most powerful particle accelerator built to date. It is a proton-proton and heavy ion collider which in 2015 and 2016 operated at an unprecedented center of mass energy of √s = 13 TeV. The Tile Calorimeter is the ATLAS hadronic calorimeter covering the central region of the detector. READ MORE

7. 5. Searches for Dark Matter and Large Extra Dimensions in Monojet Final States with the ATLAS Experiment

   Author : Olof Lundberg; Christophe Clement; Shahram Rahatlou; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle physics; bsm; gravity; extra dimensions; dark matter; ATLAS; LHC; fysik; Physics;

   Abstract : This thesis presents searches for evidence for Weakly Interacting Massive Particles (WIMPs) and Extra Dimensions in proton-proton collisions recorded by the ATLAS experiment at the CERN Large Hadron Collider (LHC). The WIMP is one of the main candidates to constitute the particle content of Dark Matter. READ MORE
