The end of this year is approaching, LHC gathered data at higher luminosity but it is since the end of August that no news is around about the status of the search of the Higgs particle. Of course, a frenzy of activity is going around at CERN and finally, something seems to move. On Monday a new conference will begin in Paris (see here). No relevant novelties are expected with respect to this talk but DG of CERN asked for updates in the mid of December (see here for other information). Besides, rumors are spreading around blogosphere that a group at CERN asked at the conference organizers a further slot to give an announcement. All this is giving the flavor that, for the end of this year, some relevant news about Higgs will come out. It could be possibly a matter of days.
I would like to resume here the situation. Latest measurements seem to exclude a standard model Higgs for almost all the range from the LEP limit of 114 GeV to near 600 GeV. At about 600 GeV ATLAS is seeing an excess. Similarly, it is possible that Higgs particle is hiding at around 140 GeV but all the excesses seen so far are no more high than so that, a no Higgs scenario is gaining support. Tevatron appears to confirm this situation. The excess at 600 GeV, if confirmed, will imply a relevant re-analysis of the standard model as, in this case, we will enter into the realm of a strongly coupled quantum field theory. I provided mathematics for this (see here and here) but it is not widely accepted by the scientific community and, in general, other methods to work with this case are not known and most of our understanding relies on lattice computations. A heavy Higgs has also been forecast by Paolo Cea and Leonardo Cosmai (see here and here) having approximately the mass near the ATLAS excess. This would make the situation quite dramatic but really exciting and will provide a strong evidence for the existence of supersymmetry. Besides, in this case, a whole spectrum of excited states of this heavy and strongly coupled Higgs will also be observed.
In view of this near approaching dates, we wish the best of luck to people at CERN and thank them for their excellent work.
