  1. 1. 11C-Acetate-PET/CT in Primary Staging of High-Risk Prostate Cancer

    Författare :Sara Strandberg; Katrine Riklund; Camilla Thellenberg-Karlsson; Jan Axelsson; Lennart Blomqvist; Jens Sörensen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; radiologi; Oncology; onkologi;

    Sammanfattning : Prostate cancer (PC) is the second most common cancer in men worldwide, affecting ~12%. Although most are clinically insignificant low-risk cancers, the more aggressive high-risk cancers require correct staging, prior to curative radiotherapy or surgery. LÄS MER

  3. 2. Measurements of the Top Quark Pair Production Cross Section and an Estimate of the DØ Silicon Detector Lifetime

    Författare :Sara Strandberg; Christophe Clément; Barbro Åsman; Steinar Stapnes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; particle physics; top quark pair production cross section; silicon radiation damage; DØ detector; Tevatron accelerator; Elementary particle physics; Elementarpartikelfysik; Physics; fysik;

    Sammanfattning : This thesis presents two measurements of the top quark pair production cross section at sqrt{s} = 1.96 TeV using data from the DØ experiment. Both measurements are performed in the dilepton final state and make use of secondary vertex b-tagging. LÄS MER

  4. 3. Non-parametric methods for functional data

    Författare :Johan Strandberg; Sara Sjöstedt de Luna; Konrad Abramowicz; Lina Schelin; Charlotte Häger; Pedro Delicado; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; functional data analysis; testing; clustering; prediction; inference; bagging Voronoi strategy; kriging; dependency; matematisk statistik; Mathematical Statistics;

    Sammanfattning : In this thesis we develop and study non-parametric methods within three major areas of functional data analysis: testing, clustering and prediction. The thesis consists of an introduction to the field, a presentation and discussion of the three areas, and six papers. LÄS MER

  5. 4. Search for Direct Top Squark Pair Production with the ATLAS Experiment and Studies of the Primary Vertex Reconstruction Performance

    Författare :Yiming Abulaiti; Sara Strandberg; Robert Wagner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SUSY;

    Sammanfattning : The ATLAS detector is one of the two largest experiments installed at the Large Hadron Collider at CERN, the European Organization for Nuclear Research. During the first run, the ATLAS detector recorded data at centre of mass energies of 7 TeV and 8 TeV, enabling many precision measurements and new physics searches. LÄS MER

  7. 5. Search for Pair-Produced Supersymmetric Top Quark Partners with the ATLAS Experiment

    Författare :Yiming Abulaiti; Sara Strandberg; Kerstin Jon-And; Isabell Melzer-Pellmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; supersymmetry; SUSY; Beyond Standard Model; stop; pMSSM; Large Hadron Collider; LHC; CERN; fysik; Physics;

    Sammanfattning : Searches for the supersymmetric partner of the top quark (stop) are motivated by natural supersymmetry, where the stop has to be light to cancel the large radiative corrections to the Higgs boson mass. This thesis presents three different searches for the stop at √s = 8 TeV and √s = 13 TeV using data from the ATLAS experiment at CERN’s Large Hadron Collider. LÄS MER
