Self-similar Properties of the Proton Structure at low x

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 F2(x,Q2) 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 < Q2 < 120 GeV2, and of Bjorken x, 6.2E-7 < x < 0.01.
