  1. 16. The Rare Decay of the Neutral Pion into a Dielectron

    University essay from Uppsala universitet/Kärnfysik

    Author : Hazhar Ghaderi; [2013]
    Keywords : rare pion decay; Mellin transform; Mellin-Barnes representation; dispersive representation; dispersion relation; Kramers-Kronig relations; Cutkosky cutting rules; Feynman Loop diagram calculations;

    Abstract : We give a rather self-contained introduction to the rare pion to dielectron decay which in nontrivial leading order is given by a QED triangle loop. We work within the dispersive framework where the imaginary part of the amplitude is obtained via the Cutkosky rules. We derive these rules in detail. READ MORE

  3. 17. Development of a tissue-like protoporphyrin IX fluorescence phantom and performance of characterisation experiments

    University essay from Biomedicinsk instrumentteknik; Tekniska högskolan

    Author : Benjamin Kistler; [2013]
    Keywords : ;

    Abstract : Background and Objective: Fluorescence spectroscopy is a potential tool for brain tumour resection surgery. The main advantages of fluorescence spectroscopy are the objective fluorescence detection, possibility to quantify the signals and high sensitivity for instance to distinguish between healthy and neoplastic tissue.

  4. 18. Analytical and Numerical Analysis of the Acoustics of Shallow Flow Reversal Chambers

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Alireza Qazizadeh; [2012]
    Keywords : ;

    Abstract : Flow reversal chambers are mainly used to accomplish a compact silencer design needed on a vehicle. Generally in this configuration the inlet and outlet ports are on the same face and the flow direction is reversed. READ MORE

  5. 19. Studies of charged Higgs bosons at the Compact Linear Collider

    University essay from Högenergifysik

    Author : Johan Relefors; [2011]
    Keywords : ;

    Abstract : The Compact Linear Collider is an electron-positron collider being developed by CERN and collaborating universities. With a center of mass energy of 3 TeV it will be used to further explore TeV scale physics after the Large Hadron Collider. READ MORE

  6. 20. Decay of a light pseudo-scalar Higgs boson to the Υ-meson and a photon

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Emil Boström; [2011]
    Keywords : standard model; Higgs boson; minimal supersymmetric standard model; Physics and Astronomy;

    Abstract : This paper is concerned with calculating the branching ratio of the decay A1 −→ Υ + γ of a pseudo-scalar Higgs boson, where Υ is a bound vector meson state of the quarks b and b-bar The results will then be applied to the b. phenomenology of the Next-to-Minimal Supersymmetric Standard Model in the case where A1 has a mass in the interval 9.
