Quantum field theory and a new universal high-energy scale

A short review of the present status of computer packages for the high order analytical perturbative calculations is presented. The mathematical algorithm and the quantum field theory methods used are briefly discussed. The most recent computer package HEPLoops for analytical computations in high energy physics up to four-loops is also discussed.

Physical Information

Abstract Dynamics of quantum field theory can be formulated by functional equations. To develop a complete functional quantum theory one has to describe the physical information by functional operations only. Such operations have been defined in preceding papers. To apply these operations to physical problems, the corresponding functionals have to be known. Therefore in this paper calculational procedures for functionals are discussed. As high energy phenomena are of interest, the calculational procedures are given for spinor field functionals. Especially a method for the calculation of stationary and Fermion-Fermion scattering functionals is proposed.

The Subject

I became a lecturer in astrophysics by chance. As I was completing my postdoc, looking at how one could do quantum field theory in the presence of gravity, I contacted various departments to see if there were any lectureships going. From departments of mathematics I was invariably told that the subject was too physical, and from physics departments that it was too mathematical. Astrophysics seemed a better bet, so I offered to give part of the Oxford undergraduate course on what was then the emerging subject of high energy astrophysics. I think I managed to keep a few pages ahead of the students most days. The result was a job offer from Leicester to teach astrophysics.
