  In the original version of the theory, the driving mechanism for spontaneous
symmetry breaking was identified in the pure scalar sector. However, this old
idea requires a heavy Higgs particle that, after the discovery of the 125 GeV
resonance, seems to be ruled out. We argue that this is not necessarily true.
If the phase transition is weakly first order, as indicated by most recent
lattice simulations, one should consider those approximation schemes that are
in agreement with this scenario. Then, even in a simple one-component theory,
it becomes natural to introduce two mass scales, say $M_h$ and $m_h$ with $m_h
\ll M_h$. This resembles the coexistence of phonons and rotons in superfluid
helium-4, which is the non-relativistic analogue of the scalar condensate, and
is potentially relevant for the Standard Model. In fact, vacuum stability would
depend on $M_h$ and not on $m_h$ and be nearly insensitive to the other
parameters of the theory (e.g. the top quark mass). By identifying $m_h=125$
GeV, and with our previous estimate from lattice simulations $M_h= 754 \pm 20
~\rm{(stat)} \pm 20 ~\rm{(syst)}$ GeV, we thus get in touch with a recent,
independent analysis of the ATLAS + CMS data which claims experimental evidence
for a scalar resonance around $700$ GeV.
