Abstract:

Conventional quantum field theory (QFT) is a method for studying structureless elementary particles, their interaction with each other and with their environment. Non-elementary particles, on the other hand, are those with internal structure or particles that are made up of elementary constituents like the nucleons, which contain quarks and gluons. We introduce a structure-inclusive algebraic formulation of quantum field theory that could handle such particles and in which orthogonal polynomials play a central role. For simplicity, we consider non-elementary scalar particles in 3+1 Minkowski space-time and, if time allows, we treat spinors having structure but in 1+1 space-time. The aim of this short exposé is to motivate further studies and research using this approach to QFT.

Warning: the talk is technical, formal and could be provocative, thus debate is encouraged.
