We find the influence of three nucleon and four nucleon forces on the nucleon characteristics in symmetric nuclear matter. We employ the finite density QCD sum rules method. The matter is considered as a system of “pion dressed” nucleons. This means that single particle nucleon states include the one pion exchanges as well as the iterated one pion exchanges. The approach provides strong hierarchy of many body forces.
