description: Supposedly, in heavy ions collisions with high energy lead to formation of quark-gluon plasma. Its formation lead to various effects, which can influence particles yields. In this pespective, collisions of helium and gold represents special interest, as collisions with no verified prove of quark-gluon plasma formation. In this thesis analysis of jet quenching's influence to eta-mesons yields in 3He+Au collisions at sqrt(x) = 200 GeV/nucleon is presented. The main characteristic of this influence is nuclear modification factors for different centralities and in transverse momentum range from 2 to 10 GeV/c. There was performed quality analysis of experimental data, was obtained yields and invariant spectra of eta-mesons, and then nuclear modification factors.
