Within this setting a very economical description of all interactions in Nature may be possible. One can assume that there is no new physics associated with any intermediate energy scale (such as Grand Unified scale or low energy supersymmetry) between the weak scale and ktr. All confirmed observational signals in favor of physics beyond the Standard Model as neutrino masses and oscillations, dark matter and dark energy, baryon asymmetry of the Universe and inflation can be associated with new physics below the electroweak scale, for reviews see
20 and
21 and references therein. The minimal model—νMSM, contains, in addition to the SM particles, 3 relatively light singlet Majorana fermions and the dilaton. These fermions could be responsible for neutrino masses, dark matter and baryon asymmetry of the Universe. The dilaton may lead to dynamical dark energy
22 and
23 and realizes spontaneously broken scale invariance which either emerges from the cosmological approach to a fixed point
22 and
24 or is an exact quantum symmetry
25 and
26. Inflation can take place either due to the SM Higgs
2 or due to the asymptotically safe character of gravity
28. Yet another part of new physics, related, for example, to the strong CP problem or to the flavor problem, may be associated with the Planck energy. In this Letter we show that this scenario leads to a prediction of the Higgs mass, which can be tested at the
LHC.
