1. Mass-Singularity Structure of QED and Perturbative Quantum Gravity Scatterings
University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : In this thesis, the mass singularities occurring in the cross-section of electron scattering processes are investigated. Two types of scatterings are studied: Quantum Electrodynamics (QED) scatterings, and Perturbative Quantum Gravity (PQG) scatterings. READ MORE

2. Asymptotic Symmetries and Faddeev-Kulish states in QED and Gravity
University essay from Stockholms universitet/FysikumAbstract : 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
