Popis:	We study the influence on the EMC effect of nucleon mass-shift and short-range correlations determining a high momentum part of the nucleon momentum distribution. The dispersion relation technique is used, the nucleus being treated as a system consisting of A nucleons. It is shown that the ratio of the structure functions F2A(x)/F2N(x) is very sensitive to the correlations in the region x≳0.3. It is also shown that decrease of the nucleon mass by ∼65 MeV, compared to the free value, leads to a quite satisfactory description of the EMC effect.
