Description

The anomalous dimension of composite ψψ is calculated in the quantum electrodynamics with additional four-fermion interaction taking into account the vacuum polarization effects. It is shown that the value of the critical index of this model coincides with that obtained from general relation connecting the critical index and anomalous dimension
