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

    Master-uppsats, Stockholms universitet/Fysikum

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

    Sammanfattning : 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. LÄS MER

  3. 2. Model building on gCICYs

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Davide Passaro; [2020]
    Nyckelord :Mathematical Physics; Geometry; Calabi Yau; Complete Intersection Calabi Yau; Generalized Complete Intersection Calabi Yau;

    Sammanfattning : 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

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :David Gaharia; [2019]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : Preface: Thank you to all the women in my life who have supported me through this process; to my mother, to my other mother (Susan), to Kara, to Jordan and, of course, to Dolly. Summary: (S)examensarbete is a journey through which I have questioned if knitting can be sexy. LÄS MER

  7. 5. Beredningsarbete av landsbygdsnät för områdena Fän, Suttene och Hermanseröd

    M1-uppsats, Högskolan Väst/Avdelningen för data-, elektro- och lantmäteriteknik

    Författare :Martin Upper; Johan Wilson; [2015]
    Nyckelord :Preparation; Cost calculation; Permit application; Field operation; Field contract.; Beredning; P2-Kalkyl; Tillstånd; Fältarbete; Markupplåtelseavtal;

    Sammanfattning : Detta examensarbete handlar om tillvägagångssättet för hur beredningsarbete utförs hos TROLK El & Tele AB. Beredningsarbetet innefattar landsbygdsnätet för tre områden, Hermanseröd, Fän samt Suttene i Munkedals kommun. Denna beredning ligger till grund för att kunna genomföra projektet från Fortum Distribution AB. LÄS MER
