  1. 1. Searches for supersymmetric long-lived particles with displaced-vertex signatures and studies of the electronic noise in the Tile Calorimeter at the ATLAS experiment

    Författare :Filip Backman; David Milstead; Christian Ohm; Stefan Richter; Sten Hellman; Kenneth Österberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : The Standard Model of particle physics is successful at describing nature on the smallest scales, but it has known flaws. These can be remedied by extended theories, such as supersymmetry. A quantum number in the supersymmetry framework is R-parity. This quantity is generally conserved, but can be violated. LÄS MER

  3. 2. Geometry Calibration of IceCube : using Photon Timing from Downgoing Muons

    Författare :Matti Jansson; Klas Hultqvist; Stefan Richter; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : The IceCube Neutrino Observatory at the South Pole has instrumented one cu-bic kilometer of ice by deploying digital optical modules (DOMs) in 86 drillholes, each containing a string of DOMs. So far IceCube has used the locationof the drill tower for the positions of DOMs in the transverse directions (x andy) to the vertical direction (z).

  4. 3. Clinical prognostic markers in chronic lymphocytic leukemia

    Författare :Stefan Norin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Chronic lymphocytic leukemia (CLL) is characterized by the accumulation of mature B lymphocytes in blood, bone marrow and lymphoid tissues. The clinical course for the individual patient is still unpredictable despite decades of research on prognostic markers and staging systems. LÄS MER

  5. 4. Topics in Complex Analysis and Operator Theory I. The shift operator on spaces of vector-valued analytic functions II. Fatou-type theorems for general approximate identities III. Preduals of Q_p-spaces

    Författare :Marcus Carlsson; Matematik (naturvetenskapliga fakulteten); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Qp-spaces; Non-tangential limits; Shift operator; Mathematics; Matematik;

    Sammanfattning : This thesis consists of six articles on three different subjects in the area of complex analysis, operator theory and harmonic analysis. Part I - "The Shift Operator on Spaces of Vector-valued Analytic Functions" consists of three closely connected articles that investigate certain operators in the Cowen-Douglas class with spectrum D - the unit disc, or equivalently, the shift operator M_z (multiplication by $z$) on Hilbert spaces of vector-valued analytic functions on D.
