We calculate one loop QCD Regge Field Theory (RFT) correction to the propagator of reggeized gluons basing on the QCD effective action of Lipatov, [1–6], and results of [7], where Dyson-Schwinger hierarchy of the equations for the correlators of reggeized gluon fields was derived. The correction is calculated entirely in the framework of RFT basing on the obtained expressions of the RFT bare triple Reggeon vertices and propagator of reggeized gluons. As the propagator of the reggeized gluons we consider separately the cases with bare transverse propagator and reggeized propagator calculated to one loop QCD precision. In both results the correction violates the reggeization property of the propagator and additionally some non-linear corrections to the propagator are obtained. Additionally, this RFT one-llop correction changes the structure of the reggeized propagator, a dependence of the propagator on the longitudinal coordinates is arising in the expressions. The further application of the obtained results is also discussed.
