  1. 21. Monte Carlo simulation and resolution study of the η → e+e− decay in the WASA-at-COSY detector

    University essay from Uppsala universitet/Kärnfysik

    Author : Walter Kenji Ikegami Andersson; [2014]
    Keywords : Resolution study; MDC; SEC; Monte Carlo; eta meson; rare decay; invariant mass;

    Abstract : A comparative study is done on the Mini Drift Chamber (MDC) and the Scintillating Electromagnetic Calorimeter (SEC), two main components of the WASA detector. The purpose of the study is to determine the most effective way to calculate the mass of the η−meson by determining the invariant mass of the final products in the η → e+e− decay. READ MORE

  3. 22. Symmetries of the Point Particle

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Alexander Söderberg; [2014]
    Keywords : symmetries; spin; classical physics; classical field theory; action; smooth spinning particle; pauli-lubanski; noether; theorem; poincare group; lorentz group; galilean transformations; relativistic; equations of motion; boost; rotation; translation; quantization; bosonic string; rigid particle; momentum; momenta; generators;

    Abstract : We study point particles to illustrate the various symmetries such as the Poincaré group and its non-relativistic version. In order to find the Noether charges and the Noether currents, which are conserved under physical symmetries, we study Noether’s theorem. READ MORE

  4. 23. Design and performance studies of a track trigger for the high luminosity LHC

    University essay from Högenergifysik

    Author : Joakim Gradin; [2013]
    Keywords : ;

    Abstract : At the high luminosity LHC the current L1 trigger of ATLAS will not be able to reduce the number of events to a level accepted by the higher level triggers. It is therefore of importance to implement new strategies of triggering to be able to continue successful operation. READ MORE

  5. 24. Charged Higgs Boson Studies in the Channel pp→a1h±→4b+l+MET in the Next-to MSSM (NMSSM) with the ATLAS Experiment

    University essay from Högenergifysik

    Author : Stephan Zimmer; [2010]
    Keywords : ATLAS; Charged Higgs; NMSSM; Beyond Standard Model; Supersymmetry; MSSM;

    Abstract : Next-to-minimal super-symmetric extensions of the Standard Model (SM) predict the existence of several non-SM like Higgs bosons. The process pp→a1h±→4b+W involves the production and the decay of a spin-0 charged Higgs boson and a CP-odd Higgs boson a1 which can have a sizable cross section in the NMSSM. READ MORE

  6. 25. Visualizing high-dimensionalplasma simulation data withVTK

    University essay from Institutionen för teknik och naturvetenskap

    Author : Naga Venkata Tallapragada; [2010]
    Keywords : plasmafysik; visualisering; dataanalys; beräkningsfysik;

    Abstract : Gamma ray bursts are flashes of gamma rays, associated with high energy explosions at cosmological distances. The main sources of gamma ray bursts are imploding stars. These bursts are mostly observed as thin beams ejecting out of these imploding stars. READ MORE
