  2. 1. Smooth particles and exotic strings

    Author : Jan Isberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : During the last few decades quantum gauge field theories in general, and the Electroweak Standard Model in particular, have been very successful in the description of the fundamental constituents of matter and their interactions. However, such models all meet with severe shortcomings, e.g. READ MORE

  4. 2. Searches for exotic stable massive particles with the ATLAS experiment

    Author : Christian Ohm; David Milstead; Torbjörn Moa; Albert Roeck; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; supersymmetry; squark; gluino; stable massive particles; long-lived particles; physics analysis; search analysis; LHC; Large Hadron Collider; fysik; Physics;

    Abstract : This thesis presents two signature-based searches for exotic long-lived particles using experimental data collected by the ATLAS experiment at the Large Hadron Collider (LHC) at CERN. At the LHC, proton-proton collisions take place at the world-record center-of-mass energy of 7 TeV and luminosities of up to  3×1033 cm-2s-1 . READ MORE

  5. 3. Studies of triggering and exotic particle searches at ATLAS, and a search for trapped monopoles

    Author : Katarina Bendtz; David Milstead; Chad Finley; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetic monopoles; ATLAS; SQUID; trigger; exotic particles; heavy long-lived particles; High Energy Physics; högenergifysik;

    Abstract : The ATLAS detector at the LHC operated through 2011 and 2012 with 7 and 8 TeV centre-of-mass energy of its colliding proton bunches, respectively. One if its main objectives is to search for physics beyond the Standard Model. READ MORE

  6. 4. Exotic phases of matter in compact stars

    Author : Fredrik Sandin; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Fysik;

    Abstract : Astrophysical observations constitute an increasingly important source of information, thanks to the high resolution of present and near-future terrestrial and orbiting observatories. Especially, the properties of matter at low temperatures and extremely high densities can only be studied by observations of compact stellar objects. READ MORE

  7. 5. Exotic phases of matter in compact stars

    Author : Fredrik Sandin; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Fysik;

    Abstract : This doctoral thesis in physics at Luleå University of Technology is devoted to the phenomenology of compact stars, and theoretical models of their interior. Particle physics has provided fundamental concepts and details needed to develop a description of matter and the evolution of the universe. READ MORE
