  1. 16. Parton Shower Algorithms - Possible Improvements

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Baptiste Cabouat; [2017]
    Keywords : Parton shower; event generators; Monte Carlo simulations; QCD; Pythia; Final-state radiation; Initial-State radiation; evolution variable; dipole; recoils; deep inelastic scattering; Physics and Astronomy;

    Abstract : In this Master thesis, two directions have been explored to improve the current parton shower algorithm of the event generator Pythia. Firstly, three choices of transverse-momentum-ordered evolution variable have been studied for final-state radiation in order to allow more flexibility within the algorithm. READ MORE

  4. 18. Path Integral for the Hydrogen Atom : Solutions in two and three dimensions

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Author : Anders Svensson; [2016]
    Keywords : physics; quantum mechanics; path integral; feynman; hydrogen atom; propagator; fysik; kvantmekanik; vägintegral; feynman; väteatom; propagator;

    Abstract : The path integral formulation of quantum mechanics generalizes the action principle of classical mechanics. The Feynman path integral is, roughly speaking, a sum over all possible paths that a particle can take between fixed endpoints, where each path contributes to the sum by a phase factor involving the action for the path.

  5. 19. Feynman Diagrams and Map Enumeration

    University essay from Uppsala universitet/Teoretisk fysik

    Author : August Egebrand; [2016]
    Keywords : ;

    Abstract : The goal of this thesis is to count how many graphs exist given a number of verticesor some other restrictions. The graphs are counted by perturbing Gaussian integralsand using the Wick lemma to interpret the perturbations in terms of graphs. Fatgraphs, a specific type of graph, are central in this thesis.

  6. 20. The kaon electromagnetic mass difference in AdS/QCD

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Jack Borthwick; [2016]
    Keywords : particle physics; AdS QCD; AdS CFT; kaon; electromagnetic mass difference; quantum field theory; Physics and Astronomy;

    Abstract : In this thesis, a holographic model for quantum chromodynamics (QCD) is used to estimate the electromagnetic contribution to the kaon mass difference. The principal ideas of the model are inspired by the AdS/CFT correspondence, which is believed to be exact. READ MORE
