Trajectories and Particle Creation and Annihilation in Quantum Field Theory
arXiv:quant-ph/0208072 · doi:10.1088/0305-4470/36/14/315
Abstract
We develop a theory based on Bohmian mechanics in which particle world lines can begin and end. Such a theory provides a realist description of creation and annihilation events and thus a further step towards a "beable-based" formulation of quantum field theory, as opposed to the usual "observable-based" formulation which is plagued by the conceptual difficulties--like the measurement problem--of quantum mechanics.
