1. 1. Search for Weakly Produced Supersymmetric Particles in the ATLAS Experiment

   Författare :Maja Tylmad; Christophe Clément; Barbro Åsman; Patrice Verdier; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; supersymmetry; chargino; neutralino; physics analysis; LHC; Large Hadron Collider; fysik; Physics;

   Sammanfattning : The Large Hadron Collider located at CERN is currently the most powerful particle accelerator and ATLAS is an experiment designed to exploit the high energy proton-proton collisions provided by the LHC. It opens a unique window to search for new physics at very high energy, such as supersymmetry, a postulated symmetry between fermions and bosons. LÄS MER

3. 2. Search for Charginos and Sleptons in ATLAS and Identification of Pile-up with the Tile Calorimeter

   Författare :Pawel Klimek; Christophe Clément; Barbro Åsman; Freya Blekman; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS experiment; particle physics; high energy physics; supersymmetry; SUSY; beyond standard model; chargino; neutralino; slepton; vector boson fusion; VBF; Tile calorimeter; TileCal; pile-up; quality factor; Large Hadron Collider; LHC; CERN; fysik; Physics;

   Sammanfattning : The standard model of particle physics (SM) describes the elementary particles and their interactions. Supersymmetry (SUSY), a symmetry beyond those included in the standard model could resolve some of the SM shortcomings. It can provide a candidate for Dark Matter and a solution to the hierarchy problem. LÄS MER

4. 3. Searches for New Physics in Single Photon Events and a Search for Charginos at the DELPHI Experiment

   Författare :Stefan Ask; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; DELPHI; single photon events; LEP; chargino search; supersymmetry; extra dimensions; Elementary particle physics; non standard neutino interactions.; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2004:Ask;

   Sammanfattning : A search for new physics using events with a single photon and missing energy has been made at the DELPHI experiment together with a search for charginos. The results were based on data collected up to and including the final year of 2000. LÄS MER

5. 4. 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

7. 5. Search for Charginos and Sleptons in ATLAS and Identification of Pile-up with the Tile Calorimeter

   Författare :Pawel Klimek; Christophe Clément; Jan Conrad; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LHC; ATLAS; TileCal; Supersymmetry; Quality Factor; fysik; Physics;

   Sammanfattning : The Large Hadron Collider (LHC) located at the European Organization for Nuclear Research (CERN) is the most powerful particle accelerator in the world in terms of collision energy and luminosity. This thesis presents a search for supersymmetric particles in proton-proton collision data recorded by the ATLAS experiment. LÄS MER
