  2. 16. 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

  4. 17. 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

  5. 18. 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

  6. 19. Searches for Higgs bosons with hadronically decaying τ-leptons : Using Grid and Cloud computing techniques

    Author : Henrik Öhman; Arnaud Ferrari; Paula Eerola; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LHC; ATLAS; Higgs; Charged Higgs; Tau lepton; 2HDM; MSSM; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : This thesis describes a measurement of the Standard Model Higgs boson coupling to fermions in decays to two τ-leptons, a search for charged Higgs bosons in decays to a τ-lepton and a neutrino, as well as the reconstruction, identification and triggering of hadronically decaying τ-leptons. The data considered are collected by the ATLAS experiment at the Large Hadron Collider. READ MORE

  7. 20. Color Screening in QCD and Neutrinos from Singlino Dark Matter

    Author : Dominik Werder; Gunnar Ingelman; Rikard Enberg; Roman Pasechnik; Hannes Jung; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QCD; Diffraction; SCI; Dark Matter; Singlino; NMSSM; Indirect Detection; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : Hard diffraction in proton collisions, where the initial state proton emerges from the interaction rather undisturbed despite a hard interaction scale, has been studied for a few decades. First observed in proton-proton collisions, the phenomenon is seen as well in deep inelastic electron-proton scattering (DIS) as a leading final state proton and a rapidity gap-region without final state particles.
