Geometric Models: E8, SO(10),(adsbygoogle = window.adsbygoogle || []).push({});

Which ansatzs will prove to be right by CERN?

1. Ali H. Chamseddine and Alain Connes , SO(10)

…. the spectral action associated with this noncommutative space unifies gravitation with the Standard Model at the unification scale.

… Therefore the bare action we obtained and associated with the spectrum of the standard model is consistent within ten percent provided the cutoff scale is taken to be _ ∼ 1015 Gev at which the action becomes geometrical.

2. A. Garrett Lisi, E8

… A non-compact real form of the E8 Lie algebra has G2 and F4 subalgebras which

break down to strong su(3), electroweak su(2) x u(1), gravitational so(3,1), the frame-Higgs, and three generations of fermions related by triality.

Everyone is trying to get away from the Planck Scale.

If the geometry is expressed at the QCD why would the cut off scale need to go to the unification scale?
