  1. 1. Mass-Singularity Structure of QED and Perturbative Quantum Gravity Scatterings

    University essay from Lunds universitet/Teoretisk partikelfysik

    Author : Santiago Londono Castillo; [2020]
    Keywords : perturbative quantum gravity; QED; mass singularities; collinear singularities; soft singularities; singularity cancellation; graviton; Physics and Astronomy;

    Abstract : 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. 2. Pair Production and the Light-Front Vacuum

    University essay from Umeå universitet/Institutionen för fysik

    Author : Ramin Ghorbani Ghomeshi; [2013]
    Keywords : Strong-Field QED; Quantum Vacuum; Schwinger Pair Production Mechanism; Dirac Forms of Relativistic Dynamics; Light-front Quantization; Zero-mode Issue; DLCQ; Worldline Approach;

    Abstract : 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. 3. Pair Annihilation in a Laser Pulse

    University essay from Umeå universitet/Institutionen för fysik

    Author : Petter Johansson; [2011]
    Keywords : Pair Annihilation; Laser Pulses; XFEL; ELI; Strong Field QED; Intense Field QED;

    Abstract : 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.
