Application of the rescaling model at small Bjorken x values

The Bessel-inspired behavior of parton densities at small Bjorken x values, obtained in the case of the flat initial conditions for Dokshitzer-Gribov-Lipatov-Altarelli-Parisi evolution equations, is used along with frozen and analytic modifications of the strong coupling constant to study the so-called European Muon Collaboration effect. Among other results, this approach allowed predicting small x behavior of the gluon density in nuclei.
