Description
Here, we present the extraction of the Parton Distribution Functions (PDFs) at
low x and at the next-to-leading order (NLO) approximation.
We show that the "sea quark distribution functions" have self-similar behavior or the "Fractal" behavior with fixed exponent at $x<0.01$. To this end, a simple parametrization for the sea quarks PDFs based on the "Fractal" approach is considered. The small $x$ experimental datasets on electron-proton ($e^-p$) and positron-proton ($e^+p$) in DIS processes at HERA for the range of $1.5< Q^2 < 650$ ($GeV^2$) and $x<0.01$ are included in this analysis. The results indicate
nice agreements between the experimental data and the theory predictions at low $x$.
