Abstract
In this work we investigate the renormalization group flow of the cosmological constant induced by the change in space-time curvature in the electroweak vacuum. We calculate the generic magnitude resulting from running in the standard model in a subtraction scheme that respects the Appelquist-Carazzone decoupling theorem. Interestingly, we find in this prescription that for a non-minimal coupling the magnitude of the generated contribution remains below the value consistent with observations.
