The "quasi boson"

The following chart shows the results of statistical elaborations on data from research conducted at today for the Higgs boson at LHC by Atlas and CMS, combined. The chart is not official (CERN have been disclosed in the conference of 13/12/11 the two graphs separately) but still, watching together is equally reliable for a qualitative assessment. In abscissa we have the mass of the Higgs (which, remember, it is theoretically unknown) and the ordinate the probability that the Higgs is manifested. This probability is obtained, in turn, by different ways of theoretically expected showing mode of the boson (various "decay channels") in various ranges of mass / energy. Since the Higgs is produced by crashes between protons that determine other products/decay mode (especially high-energy photons that are detected by calorimethers) must be purified from these data not significant for statistical purposes ("background noise") of the overall data. The green and yellow bands are the "standard deviation" (respectively equal to 1 and 2 sigma) or the indicator data scattering around the mean value of the probability distribution that governs the physical phenomenon (in this case Poisson curves ) and, therefore, the amplitude of the statistical sample and, ultimately, its credibility, greater more great the sigma itself. The horizontal line represents what, in theory, would with certainty "background noise" (data below the line).

As you can observe data present "statistical excess" in the field of mass ranging from 115 to about 120 Gev, namely the existence of a “light” Higgs boson whose existence requires, to be compatible with the standard model, even the super symmetric particles (SUSY) of which there isn't track. The conclusion of the workshop held at CERN was that data suggest the possible existence of the Higgs boson in this mass range/energy, and exclude the existence of others. The main difficulty lies in distinguishing precisely the single particle from the background noise. In the next "run" of the LHC, which, by the end of 2012, will reach Tev, should clarify the situation further.

The MT provides for "statistical peaks", as you can begin to see from the graph flatting further, taking "wavy" development, going to show un localized nature of elementary particles, as Louise De Broglie hypothesis , and their membership to the physical mass/energy fields (the Higgs field in this case) of which they are "exciting states". Ultymately you will observe the "solitons".
