Modified gravity with scale invariance and implications
by Nersessian, Nejdeh, M.S., California State University, Long Beach, 2012, 42; 1507776
Abstract (Summary)

Modified gravity that emerges from an explicitly broken scale invariant extension of the Weinberg Salam model is studied in the light of present ideas on inflation and empirical evidence on dark matter and dark energy. Inflation requires the presence of scalar fields interacting with gravitational interactions, dark matter requires the existence of matter that is non baryonic and weakly interacting, while dark energy requires the presence of either the cosmological term or vacuum energy. All these ingredients are naturally present in the scale invariant standard model.
