Bertolini, S; Santamaria, A

We show that the coupling of the ''standard'' Higgs boson to Majorons, that could lead to a very fast decay of the neutral Higgs scalar to invisible modes, can be bounded using astrophysical arguments. We discuss the relevance of this bound for low-energy phenomenology related to majoron production. The bound so obtained may also jeopardize the stability of the VEV hierarchy in the doublet and triplet majoron models if the mass of the top quark is less than the W mass. The analysis applies generally to models which exhibit (pseudo-) Golstone bosons in the spectrum. 15 refs., 1 fig.
