Abstract

We present parametrizations for the proton structure function $F_{2}$ in the next to leading order in perturbative QCD. The calculations show that the dominant term to $F_{2} (x, Q^{2})$ should grow as $x^{-\ls}$ for small $x$ values, with the exponent $\ls$ being essentially independent of $Q^{2}$ . Comparisons with the most recent H1 and ZEUS data confirm the value $\ls \sim 0.35$ obtained previously from fits to low energy data.
