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. QCD Phenomenology of Heavy Particle Dynamics

   Author : Emanuel Norrbin; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; High energy interactions; heavy quarks; QCD; charm asymmetry; hadronization; string fragmentation; colour reconnection; leptoquarks; parton shower; cosmic rays; Kosmisk strålning; högenergi; Fysicumarkivet A:2000:Norrbin;

   Abstract : In this thesis the phenomenology of Quantum Chromo Dynamics (QCD) is studied in a variety of circumstances from both perturbative and non-perturbative perspectives. The main emphasis is on the production and hadronization of heavy particles, specifically heavy quarks, gauge bosons, leptoquarks and supersymmetric particles. READ MORE

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

   Author : Andreas Ekstedt; Gunnar Ingelman; Johan Rathsman; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. Rope Hadronization, Geometry and Particle Production in pp and pA Collisions

   Author : Christian Bierlich; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; QCD; Phenomenology; Hadronization; Heavy ion collisions; Fysicumarkivet A:2016:Bierlich;

   Abstract : This thesis concerns models of high energy collisions of sub-atomic particles, and the models’ implementation in numerical simulations; so–called Monte Carlo event generators. The models put forth in the thesis improves the description of soft collisions of protons, and takes the first steps towards a new, microscopic description of collectivity in proton collisions and collisions of heavy nuclei such as lead.

7. 5. 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
