Abstract
The existence of the mixed fermion-photon condensate (epsisigma(munu)p siF(munu)BAR) of a magnetic type, breaking chiral symmetry, is shown i n the Nambu-Jona-Lasinio gauge model. The renormalization constant for the composite operator epsisigma(munu)psiF(munu)BAR is, calculated in the ladder approximation. The analytic expression for the renormalize d condensate is obtained in different domains of the phase diagram.
