Title: 
Noncommutative Geometry, Grand Symmetry and Higgs mass

Abstract: 
In the context of the spectral action and the noncommutative approach to
the standard model we describe some applications to the particle physics
world. In particular we will present a model based on a larger symmetry
that mixes gauge and spin degrees of freedom without introducing extra
fermions; with this grand symmetry it is natural to obtain the Higgs mass
in the vicinity of 126 GeV and solve the instabiliy problem. This larger
symmetry, requiring the noncommutative space to be an almost commutative
geometry, gives conditions for the breaking of this grand symmetry to the
standard model.
