# GUT-SUSY SU(5) is falsified, does SO(10) SUSY predict superpartner masses & proton de

Since non-SUSY GUT's are in danger of falsification by proton decay experiments, SUSY pushes up the half-lives of protons but even so,

GUT-SUSY SU(5) is falsified by proton decay experiments,

does SO(10) SUSY predict superpartner masses for LHC to see or observe (or alternatively, if LHC does not see superpartners at its energy scales at LHC) & proton decay half-life, how would this effect SO(10) SUSY GUT?

I heard it claimed that SO(10) SUSY GUT predicts proton half-life of 10^36 and superpartners such as the neutrilino around 200-1000GEV (within LHC luminosity) but are there any ARVIX papers to this effect?

Presumably, should experiments rule out SO(10) SUSY GUT, then string theory is pretty much ruled out as well.

The funny thing here is, were not for the attemps to falsify GUT theories, we had not got the neutrino oscillation data.

I rather like the E6SSM which is a GUT based on E6: See http://arxiv.org/abs/hep-ph/0510419 and http://arxiv.org/abs/hep-ph/0511256

We got a nice lecture on E6 yesterday, and there is not need of string-inspiration except than the dimension 26+1 (call it bosonic M-theory if you wish) appears very naturally; it is also mentioned in this abstract. Lecturer protested about putting E4, E5, E6 in the same bag -very different things, it seems- and told that the best notation for the Dynkin diagrams was teh one coming... from Bourbaki!
