NLO predictions for the growth of F_2 at small #chi# and comparison with experimental data

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"-"#lambda#"_s for small x values, with the exponent #lambda#_S being essentially independent of Q"2. Comparisons with the most recent H1 and ZEUS data confirm the value #lambda#_S#approx#0.35 obtained previously from fits to low energy data.
