Higgs is supposedly near 126 GeV.

Does anybody know the significance of the peak near 190 GeV?

The reason I ask is that Mendel Sachs (who passed away May 5th, 2012) predicted a proton mass doublet near 193 GeV.

His completion of Einstein's GR theory involves removal of the

unnecessary space and time reflection symmetry (such reflection being a non-continuous transformation) from the underlying covariance group, yielding 16 quaternion (spinor) equations, 10 of those associated with Einstein's gravity equations and the remaining 6 associated with Maxwell's electromagnetic equations.

The prediction then also follows that the proton has a heavy sister, whose mass is the order of 193 Gev.

A proton mass doublet from general relativityThis paper discusses the features of the proton mass according to the author's nonlinear, spinor field theory in general relativity. Within its context, where mass doublets are generally predicted for all spinor matter fields, it is shown, in a semi-quantitative fashion, that 1) in addition to the normal (stable) proton there is a heavier proton that has a mass of order 193 GeV and 2) a fundamental constant, g_m∼2.087·10−14 cm, that was determined earlier from a more general version of electrodynamics in which a short-range part plays a role in the nucleon domain, leads to a prediction of the normal proton mass that is within 1.0% of its empirical value.
