ENERGY AND MOMENTUM IN CHIRAL THEORIES
Journal or Book Title
ZEITSCHRIFT FUR PHYSIK C-PARTICLES AND FIELDS
We calculate the energy momentum tensor to orderE 4 in chiral perturbation theory. New terms not present in previous work enter the effective Lagrangian. We describe these and estimate the values of the new coupling constants, using the results of a disperisve analysis of the pgr andK energy momentum tensors and relying on tensor meson dominance for the spin two component. In addition, we compare our findings with the predictions of known scalar meson dominance models of the conformal anomaly.
