Energy-Momentum Tensor Improvements in Two Dimensions
arXiv:hep-th/9510145 · doi:10.1142/S021797929600060X
Abstract
We discuss some aspects of the two-dimensional scalar field, considering particularly the action for the conformal anomaly as an ``improved'' gravitational coupling, and the possibility of introducing a dual coupling, which provides a ``chiral'' energy-momentum tensor improvement.
