Energy momentum tensor in local causal perturbation theory
Description
We study the energy momentum tensor in the Bogolyubov-Epstein-Glaser approach to perturbation theory. It is found to be locally conserved for a class of theories containing to derivated fields in the interaction. For the massless φ4-theory we derive the trace anomaly of the improved tensor. (orig.)
