Abstract
We study a scalar field theory coupled to gravity on a flat background, below Plancks energy. Einsteins theory is treated as an effective field theory. Within the context of Wilsons renormalization group we compute gravitational corrections to the functions and the anomalous dimension of the scalar field, taking into account threshold effects. © 1995 The American Physical Society.File in questo prodotto:
