Self-similar properties of proton structure in the kinematic region of low Bjorken x are introduced and studied numerically. A description of the proton structure function F 2 (x, Q 2 ) reflecting self-similarity is proposed with a few parameters which are fitted to recent HERA data. The specific parameterisation provides an excellent description of the data which cover a region of four momentum transfer squared, 0.045 ≤ Q 2 ≤ 120 GeV 2 , and of Bjorken x, 6.2 · 10 −7 ≤ x ≤ 0.01 .Recent measurements of the H1 [1] and ZEUS [2] collaborations at HERA enable to study the proton structure in the region of low Q 2 1 GeV 2 where perturbative QCD has to face computation difficulties arising from the increase of the strong coupling constant α s (Q 2 ). Nevertheless, there is a number of approaches to describe the transition to low Q 2 at small x together with the region, Q 2 > 1 GeV 2 , which is described by perturbative QCD very well. Such attempts involve Reggeon exchange ideas [3], dipole interactions [4], vector meson dominance (VMD) [5], efficient parametrisations [6] and others.This letter presents a different point of view, based on the idea that the proton structure at low x is of fractal nature. Using the fractal dimension concept [7], a simple parametrisation of the proton structure function F 2 (x, Q 2 ) is obtained with a few well defined parameters. A numeric study is made using recent small x HERA data, for Q 2 between 0.045 GeV 2 and 120 GeV 2 .

“…We extend significantly the limits on squarks and gluinos, especially in the region where m g > m q . Within MLES models, for negative µ and tan β = 2, the CERN LEP limits on charginos m χ ± 1 < 86 to 45 GeV/c 2 [21] translate roughly to a limit on m 1/2 of 45 GeV/c 2 for small m 0 , and 86 GeV/c 2 for large m 0 . Our limit on m 1/2 ranges between 100 GeV/c 2 for small m 0 , and 60 GeV/c 2 for large m 0 .…”

“…Various other models focused in particular on the lower x structure function data. Haidt [ 63] showed that the F 2 (x, Q 2 ) data for x < 0.001 and 0.11 < Q 2 < 35 GeV 2 , are very well described by the simple double logarithmic expression (motivated by the dominant boson-gluon fusion term in the partonic subprocesses [ 63])…”
