Abstract We consider that the observable cosmological constant is the sum of the vacuum (Λvac) and the induced term (Λind-3m2/4) with m being the ultra-light masses ($\ap$ Hubble parameter) implemented in the theory from supergravities arguments and non-minimal coupling. In the absence of a scalar buildup of matter fields, we study its effects on spontaneous symmetry breaking with a Higgs potential and show how the presence of the ultra-light masses yields some important consequences for the early universe and new constraints on the Higgs and electroweak gauge bosons masses.
