  2. 21. Searches for a Charged Higgs Boson in ATLAS and Development of Novel Technology for Future Particle Detector Systems

    Author : Daniel Pelikan; Richard Brenner; Arnaud Ferrari; Elin Bergeås Kuutmann; Fabrizio Palla; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Charged Higgs boson; Matrix Method; ATLAS; 60 GHz; future particle detector; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : The discovery of a charged Higgs boson (H±) would be a clear indication for physics beyond the Standard Model. This thesis describes searches for charged Higgs bosons with the ATLAS experiment at CERN’s Large Hadron Collider (LHC). The first data collected during the LHC Run 1 is analysed, searching for a light charged Higgs boson (mH±.. READ MORE

  4. 22. Aspects of the ATLAS ITk Inner Tracker development for the high luminosity upgrade of the Large Hadron Collider

    Author : Jonas Steentoft; Richard Brenner; Rebeca Gonzalez Suarez; Matti Kalliokoski; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATLAS ITk; Detector instrumentation; Applied physics; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : The High Luminosity upgrade of the Large Hadron Collider (HL-LHC), necessitates that the ATLAS experiment replace their current Inner Detector (ID) system. The new Inner Tracker (ITk) will be an all silicon detector, utilising both pixel and strip sensors, with the aim of performing as well, or better than the current system - but in a much more challenging environment.

  5. 23. Exploring the Universe Using Neutrinos : A Search for Point Sources in the Southern Hemisphere Using the IceCube Neutrino Observatory

    Author : Rickard Ström; Allan Hallgren; Olga Botner; Chad Finley; Lawrence R. Sulak; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; astroparticle physics; neutrino sources; neutrino telescopes; IceCube; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : Neutrinos are the ideal cosmic messengers, and can be used to explore the most powerful accelerators in the Universe, in particular the mechanisms for producing and accelerating cosmic rays to incredible energies. By studying clustering of neutrino candidate events in the IceCube detector we can discover sites of hadronic acceleration. READ MORE

  6. 24. Dark Matter in the Galactic Halo : A Search Using Neutrino Induced Cascades in the DeepCore Extension of IceCube

    Author : Henric Taavola; Olga Botner; Allan Hallgren; Carlos Perez de los Heros; Jodi Cooley; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dark matter; WIMP; neutralino; MSSM; neutrino telescope; IceCube; DeepCore; Galactic halo; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : A search for Weakly Interacting Massive Particles (WIMPs) annihilating in the dark matter halo of the Milky Way was performed, using data from the IceCube Neutrino Observatory and its low-energy extension DeepCore. The data were collected during one year between 2011 to 2012 corresponding to 329.1 days of detector livetime. READ MORE

  7. 25. The colour of gluon interactions : Studies of Quantum Chromodynamics in soft and hard processes

    Author : Nicuşor Tîmneanu; Jochen Bartels; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Fysik; Physics;

    Abstract : Quantum Chromodynamics (QCD) is the theory of the strong interaction, one of the fundamental forces of nature. The interactions between quarks are mediated by gluons, which are the colour-charged gauge fields in QCD. READ MORE
