  In the noncommutative geometry approach to the standard model we discuss the
possibility to derive the extra scalar field sv- initially suggested by
particle physicist to stabilize the electroweak vacuum - from a "grand algebra"
that contains the usual standard model algebra. We introduce the
Connes-Moscovici twisted spectral triples for the Grand Symmetry model, to cure
a technical problem, that is the appearance, together with the field sv, of
unbounded vectorial terms. The twist makes these terms bounded, and also
permits to understand the breaking making the computation of the Higgs mass
compatible with the 126 GeV experimental value.
