1. Asymptotic Symmetries and Dressed States in QED and QCD
Master-uppsats, Stockholms universitet/FysikumSammanfattning : 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
2. Transformation of In-Flight Measured Loads to a Fatigue Test Spectrum
Master-uppsats, Linköpings universitet/Mekanik och hållfasthetsläraSammanfattning : Fatigue is a well-recognized issue in lightweight and high-performance aircraft structures. As fatigue failures have led to serious accidents and caused significant economic impact in the past, design against fatigue is crucial. LÄS MER
3. Asymptotic Symmetries and Faddeev-Kulish states in QED and Gravity
Master-uppsats, Stockholms universitet/FysikumSammanfattning : 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
