Please give a brief summary of your poster
The study of fundamental interactions in intense external fields is a broad,
interesting and incomplete area of study. Intense external fields are present in the
charged bunch collisions at accelerators, being responsible for the beamstrahlung,
pair background processes and potentially affecting all collider physics
processes. Pair annihilation in the intense fields near the surfaces of
magnetars maybe responsible for intense gamma ray bursts. The intense Coulomb
fields present in heavy ion collisions are also known to affect physics
processes. The general QFT with intense external fields is examined with
attention paid to the cancellation of IR divergences, and whether resonances
are present in the cross-sections of the second order process cross-sections
in the bound interaction picture.
