Abstract

Applying the background field method, we construct by explicit computation the leading-order nonlocal quantum correction to the on-shell effective action for \\phi ^3\ theory in six dimensions. We then use the resulting action to obtain the nonlocal correction to the energy-momentum tensor. At leading order, we find that this nonlocal correction modifies the virial current when the scalar field is minimally coupled to gravity. This is to be compared to the classically Weyl invariant case, where it only corrects the traceless part of the energy-momentum tensor.
