Great hopes that finally the signs of new physics are detected, they put in the year 2015 at Cern. Then the protons in the LHC will collide with the maximum collision energy of 14 000 GeV. Read more:

Today I read an article from which I now bring some excerpts:

 

World model: The time after the Higgs boson

The Standard Model of particle physics is probably complete with the last puzzle stone. But many questions are open. The theorists at least have already the suitable answers ready.

But the real great questions are still open. Why do exactly twelve building blocks of matter exist although nature, which surrounds us, restricts itself to only four? Why do the six quarks and six leptons let themselves be classified into three families according to their mass? Just as little particle physics is able to explain the enormous range of particle masses, from the almost massless neutrinos over the light electrons up to the top quark, which carries almost as much mass as a gold nucleus. Moreover it is unclear why the forces of nature are so differently strong and why the power of gravitation cannot be described with the help of quantum theory.

Super symmetry has though the great disadvantage that it is a pure hypothetical construct similar to the string theory. For so far not one single super symmetric particle is gone into the net of the scientists. This might change when now the properties of the supposed Higgs boson are investigated. So far it is for example unclear which spin the discovered particle has and why it has a comparatively low mass with 125 Gigaelectronvolt. Great hopes that finally the signs of new physics are detected, they put in the year 2015 at Cern. Then the protons in the LHC will collide with the maximum collision energy of 14 000 GeV. At this moment the lightest Susy particles should at least put in an appearance.
