Neutrinos of Universe and Masses of Particles

The detection and the research of the neutrinos background of Universe are the attractive problems. This problems do not seem the unpromising one in the case of the high neutrinos density that is necessary for the explanation of the nucleons-antinucleons asymmetry of Universe (the Pontekorvo’s and Smorodinsky’s hipothesis [1]). It was offered before to use the low energy neutrinos background of Universe for the explanation of the gravitational phenomena with the quantum position attracting the Casimir’s effect for this [2]. As a result it was connected the gravitational constant GN with the parameters characterizing the electroweak interactions: GN = σ/6, where σ is the scattering cross-section of neutrinos upon the particle of the macroscopic body. In particular (by the employment of the neutrinos distribution with the effective temperature T = 1.9K) the average value < σ > of the scattering cross-section will writte down as < σ >≈ 4 π kGF < ω > 2 ( 1 4 − 1 2 ξ + ξ), (0.1)
