Title Cosmological implications of quantum scale invariance
Abstract We study cosmology in scale invariant models with renormalization prescription preserving the scale invariance even at quantum level. Such models are known to be non-renormalizable and hence interpreted as effective field theory. The associated cut-off scale is evaluated and we argue that it can be high enough to justify the usual perturbative computation of effective potential. However the resultant potential is still scale invariant with some non-polynomial corrections. We apply it to a realistic model including the standard model fields and discuss how it impacts on the thermal history.
