Is it Really Higgs?

Authors: Matti Pitkanen

The discovery of a new spinless particle at LHC has dominated the discussions in physics blogs during July 2012. Quite many bloggers identify without hesitation the new particle as the long sought for Higgs although some aspects of data do not encourage the interpretation as standard model Higgs or possibly its SUSY variant. Maybe the reason is that it is rather imagine any other interpretation. In this article the TGD based interpretation as a pion-like states of scaled up variant of hadron physics is discussed explaining also why standard model Higgs - by definition provider of fermion masses - is not needed. Essentially one assumption, the separate conservation of quark and lepton numbers realized in terms of 8-D chiral invariance, excludes Higgs like states in this sense as also standard N=1 SUSY. One can however consider Higgs like particles giving masses to weak gauge bosons: motivation comes from the correctly predicted group theoretical W/Z mass ratio. The pion of M89 hadron physics is the TGD proposal for a state behaving like Higgs and its decays via instanton coupling mimic the decays of Higgs to gauge boson pairs. For this option also charged Higgs like states are prediction. The instanton coupling can however generate vacuum expectation value of pion and this indeed happens in the model for leptopion. This would lead to the counterpart of Higgs mechanism with weak bosons "eating" three components of Higgs. This is certainly a problem. The solution is that at microscopic level instanton density can be non-vanishing only in Euclidian regions representing lines of generalized Feynman diagrams. It is Euclidian pion - a flux tube connecting opposite throats of a wormhole contact which develops vacuum expectation whereas ordinary pion is Minkowskian and corresponds to flux tube connecting throats of separate wormhole contacts and cannot develop vacuum expectation. This identification could explain the failure to find the decays to τ pairs and also the excess of two-gamma decays. The decays gauge boson pairs would be caused by the coupling of pion-like state to instanton density for electro-weak gauge fields. Also a connection with the dark matter researches reporting signal at 130 GeV and possibly also at 110 GeV suggests itself: maybe also these signals also correspond to pion-like states.
