Braided Structure in 4-dimensional conformal Quantum Field Theory
Bert Schroer
Higher dimensional conformal QFT possesses an interesting braided structure which, different from the d=1+1 models, is restricted to the timelike region and therefore easily escape…
Space- and Time-Like Superselection Rules in Conformal Quantum Field Theory
Bert Schroer
In conformally invariant quantum field theories one encounters besides the standard DHR superselection theory based on spacelike (Einstein-causal) commutation relations and their H…
Particle versus Field Structure in Conformal Quantum Field Theories
Bert Schroer
I show that a particle structure in conformal field theory is incompatible with interactions. As a substitute one has particle-like exitations whose interpolating fields have in ad…
Anomalous Scale Dimensions from Timelike Braiding
Bert Schroer
Using the previously gained insight about the particle/field relation in conformal quantum field theories which required interactions to be related to the existence of particle-lik…
Polarization-Free Generators and the S-Matrix
Hans-Juergen Borchers, Detlev Buchholz, Bert Schroer
Polarization-free generators, i.e. ``interacting'' Heisenberg operators which are localized in wedge-shaped regions of Minkowski space and generate single particle states from the…
