AbstractAbstract
[en] The model in which nucleon quark sea at large distances is caused by peripheral fluctuations with π-meson emission is discussed. The results are expressed through the Wsub) (π/N(xsub(π)) probability of π-meson emission by nucleon with xsub(π) momentum fraction which is calculated in the framework of the π-meson exchange model. Distributions of anti u and anti d-quarks in a nucleon which are in well agreement with the experimental data are calculated. The factor of overlapping of various diagrams of π-meson exchange in terms of quark distributions is determined. The description of experimental data on lepton pair production in NN-collisions using the data on pair production in πN-collisions is given
