  1. 1. Asymptotic Symmetries and Dressed States in QED and QCD

    University essay from Stockholms universitet/Fysikum

    Author : Saimeng Zhou; [2023]
    Keywords : Dressed states; Large gauge transformation; Faddeev-Kulish formalism; Generalized coherent state operator; Wilson line; Infrared divergence; Asymptotic Hamiltonian; QED; QCD;

    Abstract : Infrared divergences arising in theories with massless gauge bosons have been shown to cancel in scattering amplitudes when using dressed states constructed from the Faddeev- Kulish approach to the asymptotic states. It has been established that these states are closely related to asymptotic symmetries of the theory, that is, non-vanishing gauge trans- formations at the asymptotic boundary. READ MORE

  3. 2. Model building on gCICYs

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Davide Passaro; [2020]
    Keywords : Mathematical Physics; Geometry; Calabi Yau; Complete Intersection Calabi Yau; Generalized Complete Intersection Calabi Yau;

    Abstract : Prompted by the success of heterotic line bundle model building on Complete Intersection Calabi Yau (CICY) manifolds and the new developments regarding a generalization thereof, I analyze the possibility of model building on generalized CICY (gCICY) manifolds.  Ultimately this is realized on two examples of gCICYs, one of which topologically equivalent to a CICY and one inequivalent to any previously studied examples.

  4. 3. Asymptotic Symmetries and Faddeev-Kulish states in QED and Gravity

    University essay from Stockholms universitet/Fysikum

    Author : David Gaharia; [2019]
    Keywords : Faddeev-Kulish; BMS; Bondi-Metzner-Sachs; Asymptotic Symmetries; Asymptotic States; Wilson Lines; Infrared Divergence; Bloch-Nordsieck; Large Gauge Transformations; Fock; QED; Quantum Electrodynamics; Perturbative Quantum Gravity; PQG; U 1 ; Transformations; Mandelstam Quantization;

    Abstract : When calculating scattering amplitudes in gauge and gravitational theories one encounters infrared (IR) divergences associated with massless fields. These are known to be artifacts of constructing a quantum field theory starting with free fields, and the assumption that in the asymptotic limit (i.e. READ MORE

    Abstract : Due to the nature of globalization, new strategies have been designed to break into new markets. Joint Venture is a common strategy to enter new markets and by using a Joint Venture, companies share risks and establish new contacts with local knowledge. Brazil is a market where foreign investors gain more and more interest. READ MORE
