Rigid String knot suggestions for the 125-750 GeV LHC mass and more, however without clear defined masses.
According to Rigid Quantum FFF Theory, the single closed torus shaped Higgs field particle itself is supposed to be massless,
The Higgs does not spin or emit gravitons, it oscillates and is the origin of dark energy.
The Higgs is mutable into open rigid photons and leptons.
However some open rigid photons can mutal merge by interlocking and become stringy knots to be responsible for the LHC high mass results. (see images).
More complex knots will have more mass possibly representing dark matter (micro black holes).
However in this form system I did not find more clear interlocking knots as is suggested for 125 and 750 GeV.
