1. 1. Neutrino Oscillations and Charged Higgs Bosons – Experimental Projects for Physics beyond the Standard Model

   Författare :Christian Hansen; Tord Ekelöf; Blair Ratcliff; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; CERN; LHC; ATLAS; charged; Higgs; SUSY; MSSM; oscillating; neutrino; RICH; CNGS; HPD; Elementarpartikelfysik; Elementary particle physics; Elementarpartikelfysik;

   Sammanfattning : This thesis is based on work done in two different experimental projects. The first project, the Tau RICH, is a previously proposed τ-neutrino appearance experiment for the CERN neutrino beam at the Gran Sasso laboratory in Italy. The proposed experimental concept is based on the use of focusing RICH detectors with liquid radiator (C6F14). LÄS MER

3. 2. Looking for the Charged Higgs Boson : Simulation Studies for the ATLAS Experiment

   Författare :Martin Flechl; Tord Ekelöf; Richard Brenner; Kinnunen Ritva; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; charged Higgs; tau; ATLAS; HEP; CERN; LHC; Particle Physics; Grid; Physics; Fysik; högenergifysik; High Energy Physics;

   Sammanfattning : 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. LÄS MER

4. 3. Charged particle distributions and robustness of the neural network pixel clustering in ATLAS

   Författare :Edvin Sidebo; Jonas Strandberg; Bengt Lund-Jensen; David Silvermyr; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; p p: scattering; ATLAS; LHC; charged particle: multiplicity; semiconductor detector: pixel; neural network: performance; track data analysis: cluster; charged particle: cluster; splitting; CERN LHC Coll; Fysik; Physics;

   Sammanfattning : This thesis contains a study of the robustness of the artificial neural network used in the ATLAS track reconstruction algorithm as a tool to recover tracks in dense environments. Different variations, motivated by potential discrepancies between data and simulation, are performed to the neural network’s input while monitoring the corresponding change in the output. LÄS MER

5. 4. Quark Distributions and Charged Higgs Boson Production : Studies of Proton Structure and New Physics

   Författare :Johan Alwall; Gunnar Ingelman; Johan Rathsman; Dieter Zeppenfeld; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 5. Optical Levitation of Charged Droplets

   Författare :Oscar Isaksson; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water; Optical manipulation; neutralization; Radiation Pressure; demonstration; Millikan Oil Drop experiment; evaporation;

   Sammanfattning : The development of an experimental system used to investigate charged droplets is presented. The experimental setup combines optical levitation with Millikan's classical oil drop experiment and has also been used as a mean to demonstrate fundamental physical phenomena. LÄS MER
