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. Pair Production and the Light-Front Vacuum
University essay from Institutionen för fysikAbstract : Dominated by Heisenberg's uncertainty principle, vacuum is not quantum mechanically an empty void, i.e. virtual pairs of particles appear and disappear persistently. This nonlinearity subsequently provokes a number of phenomena which can only be practically observed by going to a high-intensity regime. READ MORE

3. Pair Annihilation in a Laser Pulse
University essay from Institutionen för fysikAbstract : The thesis analyses the process of pair annihilation into one photon in a laser pulse. The theory of how to include pulse shapes in Strong Field QED and the resulting cross section is presented. The cross section is calculated and estimated for lasers of ELI and XFEL facilites.
